Don't do that. XSLT assumes that the input document is IMMUTABLE during 
the course of a tranformation, and some processors (Xalan among them) 
enforce that.

If you want to return DOM nodes from your extension, construct new nodes 
using a read/write DOM implementation -- one is included with most XML 
parsers, so this shouldn't be a problem.
