StAX & XInclude

Hi there,

I am a brute newbie to this list, but quite familiar with XML.

I started using StAX. However I quickly noticed that there is no implementation
(at least that I know) that already supports XInclude.
Therefore I wrote an adapter for XMLStreamReader that adds this support.
You can find my work here:
http://m-m-m.svn.sourceforge.net/svnroot/m-m-m/trunk/mmm-util/mmm-util-xml/src/main/java/net/sf/mmm/util/xml/stream/XIncludeStreamReader.java

Now I realized that XInclude allows XPointer references, what makes it extremely
complicated and together with StAX somewhat impossible to implement (if not the
complete DOM is cached in memory). I do not give up so easily. So I am thinking
of an implementation that supports parts of the XPointer specification.

Is there someone out there who has experience with (implementing) XPointer?
or is interested in helping out? or both?
Maybe somebody knows an open-source implementation of a loose XPointer parser I
could use?

Currently I am about to write a new parser and another XMLStreamReader facade
for the XPointer selection view. Since I am always looking for generic solutions
I want to create an API for a parsed XML node selection expression and parsers
for both XPath and XPointer. Is someone familiar enough with these two animals
in order to let me know where my intention is going to fail right away or if
this could work out and make sense?

Best regards
  Jörg
