Thanks Ed,
Instance by instance transformation is fine, except the XML's
corresponding EMF model has 40 classes; the transformation is already
defined in the XSLT language by a third party. I wish to use this XSLT
and perform automatically in my application. The more I look into it, I
can be totally disconnected from EMF and use the JAXP API to perform my
transformations.

Mircea,
XSLT is useful for syntactic XML transformation. It's not so useful for
dealing with typed non-containment references which are common in
models. For example, I think it would be virtually impossible to do an
XSD to Ecore transformation using XSLT because the semantic resolution
of QNames via imports and includes is vital for doing this mapping in a
meaningful way...
