We already plan to note in the draft that the XPath data model of itself is insufficient to represent relative URIs correctly. This also applies to minimal DOM implementations. The XSLT data model is sufficient, but needs to be made xml:base-aware. > That would make it impossible for an XSLT transform > to correctly absolutize URI's or generate xml:base attributes > in documents that had external entities that had different > base URI's (until something like the resolve function > suggested in features under consideration is available). This capability is represented by an item under Appendix G (features under consideration for future versions) in the XSLT draft. > The xml:base in the following example would only come into > play in an entity expanding processor, but would result in > URI references in the entity to be uniformly interpreted. > > <!DOCTYPE ...[ > <!ENTITY xmlconf SYSTEM 'xmlconf/xmlconf.xml'> > ]> > <TESTSUITE> > <TESTCASES xml:base="xmlconf/"> > &xmlconf; > </TESTCASES> > </TESTSUITE> This may work in many situations. - Jonathan Marsh
