E. Support of XInclude in XMLmind XSL Utility

Unlike XMLmind XML Editor, XMLmind XSL Utility delegates to Xerces, its XML parser, the task of transcluding XInclude elements. This means that, compared to XMLmind XML Editor, XMLmind XSL Utility has a number of limitations related to the support of XInclude. The two main limitations are:

A XML document cannot include a part of itself. That is, in an xi:include element, the href attribute cannot be empty or missing.
The xpointer attribute of an xi:include element cannot refer to the ID of the included element, unless
- the document containing the included element conforms to a DTD (specified in this document using <!DOCTYPE>);
- OR the ID attribute is xml:id (like in DocBook 5^[3]).
When this is not the case, you must limit yourself to including the root element (xpointer="element(/1)) of the document modules.

^[3]DocBook 4 is specified by a DTD. DocBook 5 is specified by a RELAX NG schema.
