If I may jump into the discussion at that stage, I'd like to remind that
XInclude and RNG include have very different semantics.

That's something that has been discussed in the context of W3C XML
Schema on xml-dev
(http://lists.xml.org/archives/xml-dev/200011/msg00082.html) and that I
have covered in my two books
(http://books.xmlschemata.org/relaxng/relax-CHP-10-SECT-4.html).

The meaning of the RNG include pattern happens to be a merge of two
grammars and you'd have a very different result if you replaced it with
an XInclude.

In fact, the RNG pattern which comes closest to XInclude is the
externalRef pattern.

sponsor to cover my expenses which is unlikely...).
