Internally, XSLTC will traverse a DOM
tree and generate SAX events to populate a DTM representation of the input,
so going to the trouble of constructing a DOM would probably be more costly
than using a URIResolver whose resolve method returns a SAXSource.

It's possible to return a DTMAxisIterator
(upcast to an Object) from a extension function in XSLTC, but doing that
might be getting you deep into the internals of DTM.  If you have
any concerns about the potential for future incompatibilities, I would
suggest that you not do something like that.

Thanks,
