If you are authoring DocBook 5 documents, insert an

`equation`

,`informalequation`

or`inlineequation`

containing a MathML`mml:math`

child element into your document, then edit the contents of this`mml:math`

child element normally, using the Edit tool and/or the MathML tool (see below).In order to insert insert an

`equation`

,`informalequation`

or`inlineequation`

containing a MathML`mml:math`

child element into your DocBook 5 document,Use the Edit tool and choose one of the

`equation(mathml)`

,`informalequation(mathml)`

or`inlineequation(mathml)`

element templates.OR use the "Add MathML Equation" found in the DocBook tool bar.

Same approach if you are authoring a DITA topic or an XHTML 5 page.

For all document types other than DocBook 5, DITA topics and XHTML 5 (DocBook 4, XHTML 1.

, etc), you must treat MathML as if it were a graphics format such as SVG or PNG.`x`

Unlike what happens for DocBook 5 documents, DITA topics and XHTML 5 pages, you'll not be able to directly edit the MathML elements, but if you install this MathML add-on (which depends on the add-on called "JEuclid image toolkit plug-in" — see 5), the MathML elements will be properly rendered on screen and also properly converted to formats such as HTML, PDF, RTF, etc.

In practice, this means:

Create a standalone MathML document using MathML, "Inline Math" or "Math Block".

→ ,Reference this MathML document in the proper ``image element'':

DocBook 4 example

`<imagedata fileref="equations/equation1.mml"/>`

XHTML 1.

example`x`

`<img src="equations/equation1.mml"/>`
