Thanks. I already saw that from a previous posting.
I guess you acknowledge that XQuery does not have
a standard built in feature to reference other files.

I think that it is important to extend QEXO in a way which will not
promote xql code that is tied to the language implementation.
For example the Oracle implementation is full with proprietary extensions.
Not very good.
Makes XQuery look weak as a language.
So a document or a discussion thread on how to extend it to call Java
methods will be nice.


Best,
