## Chapter 4. XSLT stylesheets parameters

### Parameters common to all stylesheets

##### Note
• Parameters marked using this icon are system parameters. They are automatically specified by the application executing the XSLT stylesheets. Such system parameters must not be specified by the end-user. Such system parameters are documented here only because the end-user may see them referenced in some configuration files.
• Parameters marked using this icon are pseudo-parameters. They may or may not be passed to the XSLT stylesheets, but the important thing to remember is that they are also interpreted by ditac itself. By consequence, you cannot specify them in an XSLT stylesheet which customizes the stock ones (as explained in Part II, Chapter 9, Section 2).

extended-toc
Allowed values are: 'frontmatter', 'backmatter', 'both', 'none'.
Default value: 'none'.
Allows to add <frontmatter> and <backmatter> <topicref>s to the Table of Contents (TOC) of a document.
Note that the @toc, @navtitle, @locktitle, etc, attributes are applied normally to <frontmatter> and <backmatter> <topicref>s when an extended TOC is generated.
external-resource-base
Allowed values are: '', an URL ending with "/" or '#REMOVE'.
Default value: '#REMOVE' for EPUB 2 and EPUB 3, '' for all the other output formats.
Specifies how to resolve <xref> or <link> elements having an external @scope attribute and a relative @href attribute. Example of such <xref> elements: <xref scope="external" format="java" href="src/Test.java">Test.java</xref>.
''
Do not resolve the @href attribute. In this case, the external resource files are expected to be copied “by hand” to the output directory.
An URL ending with "/"
This URL is prepended to the value of the @href attribute.
'#REMOVE'
The <xref> or <link> element is processed as if it did not have an @href attribute.
highlight-source
Allowed values are: 'yes' and 'no'.
Default value: 'yes'.
Allows to turn off syntax highlighting in elements specializing <pre>.
By default, syntax highlighting is turned on for all elements specializing <pre> and having an @outputclass attribute equals to language-c, language-cpp, language-csharp, language-delphi, language-ini, language-java, language-javascript, language-m2, language-perl, language-php, language-python, language-ruby, language-tcl.

This parameter specifies which text to generate for a <link> element, when this <link> element has no <linktext> child element or when this <linktext> child element is empty.
Similar to above parameter xref-auto-text but for <link> elements.
note-icon-list
List of type attribute values separated by whitespace.
Default value: 'attention caution danger fastpath important note notes remember restriction tip'.
Specifies the type (attribute @type) of the <note> elements for which icons should be used rather than text in order to represent note labels.
Ignored unless use-note-icon='yes'.
number
List of values separated by whitespace. Allowed values are: 'topic', 'chapter-only', 'table', 'fig', 'example', 'equation-figure', 'all'.
Default value: '' (number nothing).
Specifies which elements are to be numbered.
'all' is a short form for 'topic table fig equation-figure'.
'chapter-only' means: number topics, but only those referenced in a bookmap as <part>, <chapter> and <appendix>.
##### Note
Please note that 'all' does not include 'example'. If you want to number all formal elements including examples, then you must specify 'all example'.
number-separator1
String.
Default value: '.'.
The string used to separate the hierarchical number of topics acting as sections.
number-separator2
String.
Default value: '-'.
The string used to separate the hierarchical number of figures, tables, examples and equations.
When possible, the number of figure, table, example or equation is made relative to the number of the ancestor chapter or appendix. This gives for example (for descendants of chapter 5): Figure 5-1. Title of first figure of chapter 5, Figure 5-2. Title of second figure of chapter 5, etc.
mark-important-steps
Allowed values are: 'yes' and 'no'.
Default value: 'no'.

Default value: 'no'.
Normally topics which are descendants of chapters (that is, topics referenced in a bookmap as <chapter>) are numbered as follows: 1. Title of first section, 1.1. Title of first subsection, etc.
Specifying prepend-chapter-to-section-number='yes' prepends the number of the chapter ancestor to the section number. This gives for example (for descendants of chapter 5): 5.1. Title of first section, 5.1.1. Title of first subsection, etc.
remedy-number-format
Allowed values are: 'I', 'i', 'A', 'a', '1'.
Default value: 'A'.
In a <troubleshooting> topic, multiple <remedy> elements having no title are given numbers formatted using this format.

Example: 'fig equation-figure table'.
Default value: ''.
Specifies which elements should have their titles displayed after their bodies.
title-page
Allowed values are: 'auto', 'none' or the URI of a custom title page.
Default value: 'auto'.
Specifies the kind of title page'' (contains the title of the document, its author, etc) to be generated before the actual contents of the document.
'auto'
Automatically generate a title page based on the title and metadata of the map.
'none'
Do not generate a title page.
URI of a custom title page
Specifies the URI of a custom title page. If the URI is relative, it is relative to the current working directory of the user.
This custom title page is an XHTML file for XHTML-based formats (XHTML, HTML Help, etc). This custom title page is an XSL-FO file for FO-based formats (PDF, RTF, etc). Such custom title pages are generally hand-written.
• The child nodes of the body element of the custom XHTML title page are wrapped in a div contained in the XHTML/HTML file being generated by the XSLT stylesheet.
Do not add a <!DOCTYPE> to such custom XHTML title page because otherwise, the XSLT stylesheet may fail loading it.
• The child nodes of the first fo:flow[@flow-name='xsl-region-body'] element of the custom XSL-FO title page are wrapped in a fo:block contained the XSL-FO file being generated by the XSLT stylesheet.
title-prefix-separator1
String.
Default value: '. '.
The string used to separate the number of an formal object from its title.
use-note-icon
Allowed values are: 'yes' and 'no'.
Default value: 'no'.
Specifies whether icons should be used rather than text in order to represent the label of a <note> element.
watermark-image
URI. If the URI is relative, it is relative to the current working directory of the user.
No default value.
Specifies an image file which is to be used as a watermark in all the pages comprising the output document. See also parameter watermark.
If you need this feature when generating RTF, WordprocessingML, Office Open XML (.docx), OpenDocument (.odt), please make sure to use XMLmind XSL-FO Converter v5.3+.
xref-auto-text
List of values separated by whitespace. Allowed values are: 'number' and 'text'.
Default value: 'number'.
This parameter specifies which text to generate for an <xref> element, when this <xref> element contains no text at all(2).
Let's suppose that an <xref> element containing no text at all points to a topic titled "Installation".
Because the <xref> element points to an element having a <title> child element, ditac may use this title as a starting point for the generated text.
Now let's suppose that topics are numbered and that the number of the "Installation" topic is "Chapter 5".
The text generated for this <xref> element is thus:
If xref-auto-text='number'
Chapter 5
If xref-auto-text='text'
Installation
If xref-auto-text='number text'
Chapter 5. Installation
Note that this specification is just a hint because ditac needs anyway to generate some text. For example, if topics are not numbered and xref-auto-text='number', the generated text will be "Installation".
xsl-resources-directory
URL. A relative URL is relative to the output directory.
Default value: 'resources/' resolved against the directory which contains the XSLT stylesheets.
Most XSLT stylesheets generate files which reference resources such as icons or CSS stylesheets. This parameter specifies the target directory which is to contain such resources.
If this directory does not exist, it is automatically created.
If this directory does not already contain the resources needed by the XSLT stylesheets, such resources are automatically copied to this directory.
The default value of this parameter is something like file:/opt/ditac/xsl/xhtml/resources/ for the stylesheets generating XHTML. URL file:/opt/ditac/xsl/xhtml/resources/ specifies an existing directory containing basic.css, note.png, important.png, etc. This means that by default, no directory is created and no resource is copied.
If the value of this parameter is an absolute URI, then ditac assumes that no resource directory is to be created and no resource is to be copied because this has already been done by the user.
##### Important
• Explicitly specifying something like xsl-resources-directory='res' is almost always required when generating files having an XHTML/HTML based format (XHTML, HTML Help, etc).
• Explicitly specifying something like xsl-resources-directory='res' is almost never required when generating files converted from XSL-FO (PDF, RTF, etc).

### Parameters common to the stylesheets that basically generate XHTML or HTML

This applies to the stylesheets that generate XHTML, HTML, Web Help, Java™ Help, HTML Help, Eclipse Help, EPUB.
Parameter Value Description
Allowed values are: 'yes' and 'no'.
Default value: 'yes'.
Specifies whether an A-Z list should be added at the beginning of the back-of-the-book index.
chain-pages
Allowed values are: 'none', 'top', 'bottom' or 'both'.
Default value: 'none'.
Specifies whether a header and/or a footer containing navigation icons should be generated in order to link together all the HTML pages.
##### Note
There is no need to specify a value other than 'none' when generating Web Help, HTML Help, Eclipse Help, EPUB and Java™ Help.
chain-topics
Allowed values are: 'yes' and 'no'.
Default value: 'no'.
Specifies whether navigation icons should be generated in order to link together all the topics.
##### Note
There is no need to specify a value other than 'no' when generating Web Help, HTML Help, Eclipse Help, EPUB and Java™ Help.
css
URL.
Default value: ''.
Specifies which CSS stylesheet to use. Has priority over the CSS stylesheet specified by the css-name parameter.
An end-user wishing to use a custom CSS must typically:
1. Import the basic.css stock stylesheet in its own custom.css as follows:
@import url(basic.css);
2. Invoke ditac with the following parameters: xsl-resources-directory='res', css='res/custom.css'.
3. Copy by hand custom.css to output_dir/res/ after ditac has finished its job.
##### Restriction
Not supported by the stylesheets that generate EPUB.
css-name
URL basename relative to the directory specified by parameter xsl-resources-directory.
Default value: 'basic.css'; 'javahelp.css' when the output format is Java™ Help.
Specifies which CSS stylesheet to use. This CSS stylesheet is expected to be found in the resources directory.
##### Restriction
Not supported by the stylesheets that generate EPUB.
default-table-width
A percentage, typically something like '100%' or '90%'.
Default value: '' (as narrow as possible).
The default width of <table> and <simpletable> elements.
Length. A length may have a unit. Default is px.
Default value: '10'.
The height of the “opens in new window” icon.
Basename.
Default value: 'new_window.png'.
The basename of the “opens in new window” icon. This icon is found in the resources directory.
Length. A length may have a unit. Default is px.
Default value: '10'.
The width of the “opens in new window”' icon.
format-to-type
Zero or more DITA format/MIME type pairs. Example: "txt text/plain xml application/xml html text/html".
Default value: '', which means that DITA xref/@format is not converted to XHTML a/@type.
Allows to map DITA xref/@format to XHTML a/@type.
Using default empty value, <xref scope="external" format="txt" href="http://acme.com/info.xyz"> is converted to <a href="http://acme.com/info.xyz" target="_blank">. The fact that file extension ".xyz" is unknown may cause problems when attempting to navigate or download file "info.xyz" using a Web browser.
If -p format-to-type "txt text/plain" is passed to ditac then <xref scope="external" format="txt" href="http://acme.com/info.xyz"> is converted to <a type="text/plain" href="http://acme.com/info.xyz" target="_blank">, which is better.
generator-info
String
Default value: 'XMLmind DITA Converter VERSION'.
The name of the software which has been used to create the HTML pages.
Specify an empty string if you don't want to have a <meta name="generator" content="XXX"/> element added to your HTML pages.
Allowed values are: 'yes', 'no' and 'auto'.
Default value: 'auto' for XHTML and its variants; 'yes' for Web Help, Java Help, HTML Help, Eclipse Help and EPUB
If 'yes', do not generate the navigation links corresponding to topicref attribute @collection-type.
If 'no', generate the navigation links corresponding to topicref attribute @collection-type.
If 'auto', generate the navigation links corresponding to topicref attribute @collection-type, unless chain-topics=yes.
javascripts
String. List of URLs separated by whitespace.
Default value: ''.
The URLs specified in this parameter must point to JavaScript files. These URLs are converted to <script> XHTML elements added to the <html>/<head> elements of the XHTML files generated by ditac.
Note that an URL may end with ';async', ';defer' or a combination of both flags. These flags are translated to the corresponding attributes of the <script> element. Example:
https://cdn.mathjax.org/mathjax/latest/¬
MathJax.js?config=MML_CHTML;async
is translated to:
<script type="text/javascript" async="async"
src="https://cdn.mathjax.org/mathjax/latest/¬
MathJax.js?config=MML_CHTML">
</script>
mathjax
Allowed values are: 'yes', 'no' and 'auto'.
Default value: 'no'.
Very few web browsers (Firefox) can natively render MathML. Fortunately, there is MathJax . MathJax is a JavaScript display engine for mathematics that works in all browsers.
'yes'
Add a <script> XHTML element loading MathJax to the <html>/<head> elements of all XHTML files generated by ditac.
'auto'
Same as 'yes', but add <script> only to generated XHTML files containing MathML.
Ignored by all XHTML-based formats but XHTML and Web Help.
mathjax-url
String.
Default value: the URL pointing to the MathJax CDN, as recommended in the MathJax documentation.
The URL allowing to load the MathJax engine configured for rendering MathML.
Ignored unless parameter mathjax is set to 'yes'or 'auto'.
Allowed values are: 'yes' and 'no'.
Default value: 'no'.
Specifies whether an external link should be marked using a “opens in new window” icon.
Length. A length may have a unit. Default is px.
Default value: '16'.
The height of a navigation icon.
String.
Default value: '.png'.
The suffix of a navigation icon.
The root names of navigation icons are fixed:
• first, first_disabled,
• last, last_disabled,
• next, next_disabled,
• previous, previous_disabled,
• parent, parent_disabled,
• child, child_disabled.
For example, if note-icon-suffix='.svg', the default resources directory is expected to contain first.svg, first_disabled.svg, last.svg, etc.
In principle, there is no need for an end-user to specify any of the navigation-icon-suffix, navigation-icon-width or navigation-icon-height parameters.
Length. A length may have a unit. Default is px.
Default value: '16'.
The width of a navigation icon.
screen-resolution
Positive integer.
Default value: '96'.
The resolution of the screen in dot per inch (DPI). This resolution is used to convert image dimensions such as 3cm to pixels.
xhtml-mime-type
A MIME type without a parameter such as 'text/html', 'application/xhtml+xml', 'application/xml' or the empty string ('').
Default value: 'text/html'.
Applies to all the XHTM-based formats (XHTML, EPUB), not to the HTML-based formats (Web Help, Java™ Help, HTML Help, Eclipse Help).
By default ('text/html'), serve XHTML as HTML.
Specify 'application/xhtml+xml' if you prefer to serve XHTML as XML.
Specify an empty string if you prefer not to generate <meta http-equiv="Content-Type"...>.
##### Tip
Web browsers such as Firefox or Opera will not render the MathML embedded in XHTML, if this XHTML is served as HTML. Therefore when your DITA document contains MathML equations, you'll have to generate ".xhtml" files (".html" files won't work) and also, preferably, to specify xhtml-mime-type="application/xhtml+xml" or xhtml-mime-type="".

### Parameters common to the stylesheets that generate Web Help, Java™ Help, HTML Help, Eclipse Help and EPUB

Parameter Value Description
Allowed values are: 'yes' and 'no'.

• Ignored by the stylesheets that generate Web Help and EPUB.
number-toc-entries
Allowed values are: 'yes' and 'no'.
Default value: 'yes' for Web Help, 'no' for the other formats.
If 'yes', number the TOC entries. No effect unless the number parameter is used to specify that topics should be numbered.

Default value: no. Specifies whether all jQuery files should be copied to _wh/jquery/, where _wh/ is the directory containing the other Web Help files. By default, the jQuery files are accessed from the Web (typically from a CDN). Note that this parameter is applied after JQuery and JQueryUI have been possibly customized using parameters jquery, jquery-ui, jquery-css, jquery-theme and jquery-custom-theme. For example, "-p jquery-theme cupertino -p local-jquery yes" copies the Cupertino CSS files to _wh/jquery/. wh-layout The name of a layout. Default value: classic. Selects a layout for the generated Web Help. For now, only 2 layouts are supported: classic and simple. wh-use-stemming yes or no. Default value: yes.

By default, stemming is used whenever possible, that is, when the main language of the document can be determined; when this main language is one of: Danish, Dutch, English, Finnish, French, German, Hungarian, Italian, Norwegian, Portuguese, Russian, Spanish, Swedish, Romanian, Turkish. The main language of the document is specified by the @xml:lang attribute found on the root element of DITA map being converted; otherwise using the -lang command-line option; otherwise, it is assumed to be "en". wh-user-css Filename or absolute URI of a CSS file. A relative filename is relative to the current working directory. Specifies the user's CSS stylesheet which is to be added to each page of the Web Help. This file is copied to output_directory/_wh/user/. Sample user's CSS wh_resources/header_footer.css as used in the following example: -p wh-user-header ¬ wh_resources/header.html -p wh-user-footer ¬ wh_resources/footer.html -p wh-user-css ¬ wh_resources/header_footer.css -p wh-user-resources ¬ wh_resources/header_footer_files wh-user-footer Filename or absolute URI of an XHTML file. A relative filename is relative to the current working directory. Specifies the user's footer which is to be added to each page of the Web Help. The content of the  element of wh-user-footer is inserted as is in the found in each page of the Web Help. Same remark as for parameter wh-user-header about the resources referenced by a user's footer. Sample user's footer wh_resources/footer.html as used in the following example: -p wh-user-header ¬ wh_resources/header.html -p wh-user-footer ¬ wh_resources/footer.html -p wh-user-css ¬ wh_resources/header_footer.css -p wh-user-resources ¬ wh_resources/header_footer_files wh-user-header Filename or absolute URI of an XHTML file. A relative filename is relative to the current working directory. Specifies the user's header which is to be added to each page of the Web Help. The content of the  element of wh-user-header is inserted as is in the found in each page of the Web Help. If a user's header references resources (e.g. image files), then these resources must either be referenced using absolute URLs or these resources must be found in a user's resource directory and parameter wh-user-resources must be specified. Example: The user's resource directory is called header_footer_files/ and contains header_footer_files/logo100x50.png. ditac is passed parameters: -p user-resources PATH_TO/header_footer_files and -p user-header PATH_TO/header.html. header.html looks like this:  ... ... ... Notice the path used to reference logo100x50.png. Sample user's header wh_resources/header.html as used in the following example: -p wh-user-header ¬ wh_resources/header.html -p wh-user-footer ¬ wh_resources/footer.html -p wh-user-css ¬ wh_resources/header_footer.css -p wh-user-resources ¬ wh_resources/header_footer_files wh-user-resources Filename or absolute "file:" URI of a directory. URI schemes other than "file" (e.g. "http") are not supported for this parameter. A relative filename is relative to the current working directory. Specifies a user's resource directory which is to be recursively copied to output_directory/_wh/user/. This directory typically contains image files referenced by the user's header, footer or CSS stylesheet. Sample user's resource directory wh_resources/header_footer_files/ as used in the following example: -p wh-user-header ¬ wh_resources/header.html -p wh-user-footer ¬ wh_resources/footer.html -p wh-user-css ¬ wh_resources/header_footer.css -p wh-user-resources ¬ wh_resources/header_footer_files whc-index-basename URL basename. Default value: 'whc_index.xml'. Basename of the Index XML input file of XMLmind Web Help Compiler. In principle, there is no need for an end-user to specify this parameter. whc-toc-basename URL basename. Default value: 'whc_toc.xml'. Basename of the TOC XML input file of XMLmind Web Help Compiler. In principle, there is no need for an end-user to specify this parameter.

Specify 'no' if you don't need this compatibility. generate-epub-trigger Allowed values are: 'yes' and 'no'. Default value: 'yes'. Only applies to EPUB 3. Specify 'no' if your EPUB 3 reader does not support epub:trigger yet. When generate-epub-trigger=no, ditac generates an @onclick attribute containing simple JavaScript code and declares the containing XHTML 5 page as being scripted.

### Parameters specific to the stylesheets that generate XSL-FO

The XSL-FO file generated by the XSLT stylesheets is converted to PDF, PostScript®, RTF, WordprocessingML, Office Open XML (.docx), OpenOffice/LibreOffice (.odt) by the means of XSL-FO processors such as Apache FOP , RenderX XEP , Antenna House XSL Formatter or XMLmind XSL-FO Converter .

The root name of a note icon should be identical to the value of the @type attribute it represents. For example, if note-icon-suffix='.svg', the default resources directory is expected to contain note.svg, important.svg, caution.svg, etc. In principle, there is no need for an end-user to specify any of the note-icon-suffix, note-icon-width or note-icon-height parameters. note-icon-width Length.

When both page-ref-after and page-ref-before are specified as the empty string, in fact, this specifies that the generated string must be the localized equivalent of "on page". page-ref-before String. Default value: ''. Separates the text of an  or  element from the page number it points to. Ignored unless show-xref-page='yes' or show-link-page='yes'. page-top-margin Length.

Default value: 'A4'. A convenient way to specify the size of the printed page. It is also possible to specify a custom paper type by ignoring the paper-type parameter and directly specifying the page-width and page-height parameters. pdf-outline Allowed values are: 'yes' and 'no'. Default value: 'no'. Specifies whether PDF bookmarks should be generated. Supported by the 'XEP' , 'FOP' and 'AHF' XSL-FO processors. Not relevant, and thus ignored by 'XFC'. show-external-links Allowed values are: 'yes' and 'no'. Default value: 'no'. Specifies whether the external URL referenced by an  or  element should be displayed right after the text contained by this element. Example: show-external-links='yes'causes Oasis to be rendered as follows: Oasis [http://www.oasis-open.org/]. show-imagemap-links Allowed values are: 'yes' and 'no'. Default value: 'yes'. Specifies whether a numbered list should be generated for an  element, with one list item per  element. A list item contains the link specified by the  element. No list items are generated for “dead areas” ( elements specifying no link at all). show-link-page Allowed values are: 'yes' and 'no'. Default value: 'no'. Same as show-xref-page but for  elements. show-xref-page Allowed values are: 'yes' and 'no'. Default value: 'no'.

Specifies whether the document should be printed double sided. ul-li-bullets A string containing one or more single characters separated by whitespace. Default value: '• –' (BULLET, EN DASH). Specify which bullet character to use for an 
/
•  element. Additional characters are used for nested 
•  elements. For example, if ul-li-bullets="* - +", "*" will be used for 
/
•  elements, "-" will be used for 
/
•  elements contained in a 
/
•  element and "+" will be used for 
/
•  elements nested in two 
/
•  elements. Changing the value of this parameter may imply changing the font-family attribute of the attribute-set ul-li-label. unordered-step-bullets A string containing one or more single characters separated by whitespace. Default value: '•' (BULLET, EN DASH). Specify which bullet character to use for a / element. Additional characters are used for nested / elements. Changing the value of this parameter may imply changing the font-family attribute of the attribute-set unordered-step-label. watermark Allowed values are one or more of 'blank', 'title', 'toc', 'booklist', 'frontmatter', 'body', 'backmatter', 'index', 'all' separated by whitespace. Default value: 'all'. Specifies which pages in the output document are to be given a watermark. By default, all pages are given a watermark. If for example, parameter watermark is set to 'frontmatter body backmatter', then only the pages which are part of the front matter, body and back matter of the output document are given a watermark. The title page, TOC pages, etc, are not given a watermark. No effect unless parameter watermark-image is specified. xfc-render-as-table A string containing zero or more DITA element names separated by whitespace. Default value: 'note'. Specifies whether XMLmind XSL-FO Converter should render the s representing specified DITA elements as s. This parameter enables a workaround for a limitation of XMLmind XSL-FO Converter: a  having a border and/or background color and containing several other blocks, lists or tables is very poorly rendered in RTF, WML, DOCX and ODT.

 (1) Unlike a filename, an URL must contain properly quoted characters. For example, do not specify 'Hello world.htm', instead specify 'Hello%20world.htm'.
 (2) This implies that the xref-auto-text parameter is ignored when an  element contains some text.
