This may be a set of tools you want to have, but I have strong doubts
that this tool makes sense as a general XML facility.  It seems to blur
the logical/entity models quite severely, and keeps entity issues alive
much further into XML processing than was previously the case.  

Its lack of a clear processing model (when do these things get processed
and what is there relation to other W3C specs) and its content-polluting
fallback suggest some serious potential for chaos.

Adding this to core of XML, as some have suggested for an XML 2.0, seems
like a good way to ensure that developers are as mystified by missing
content in XML 2.0 (per XInclude) as they were in XML 1.0 (per NV
parsers and external entities).  If anything, XInclude seems likely to
afflict a lot more of these kinds of problems.
