This is no more true than in XSLT 1.0.

And you can do the same thing with externally-implemented extensions in XSLT 
1.0.

It is only as small as the Java implementor's (and indeed any language's 
implementor's) willingness to collaborate.

Make this disctinction if you like, but all these issues can be dealt with 
just as effectively outside the core XSLT spec.
