Creates a document set factory and registers it with XMLmind XML Editor. Checking Tools → Use as Master Document in XMLmind XML Editor - Online Help automatically creates and maintains a document set.

When attribute autoCreate is specified as true, there is no need to explicitly check Tools → Use as Master Document. Such documents are automatically made master documents. This is the case of DITA maps, DocBook 5.1+ assemblies, Ebooks, that is, all kinds of maps.

Child elements of documentSetFactory:

An empty documentSetFactory element may be used to unregister currently registers a document set factory.

DITA map example:

<documentSetFactory autoCreate="true">
  <class>com.xmlmind.xmleditext.dita.TopicSetFactory</class>
</documentSetFactory>

DocBook 5 example:

<documentSetFactory>
  <class>com.xmlmind.xmleditapp.docset.modulardoc.ModularDocumentFactory</class>
</documentSetFactory>

Note that class com.xmlmind.xmleditapp.docset.modulardoc.ModularDocumentFactory is not specific to DocBook 5. It may be used for any kind of modular document which makes use of inclusion schemes supported by XMLmind XML Editor.
