Actually, I thought it did! I thought we had an adapter for this. Am I
mistaken?

The proxy mechanism is built into the design of the DTM components. It
is something that you get automatically. You don't need to do anything.
The extension mechanism does not support extensions returning a
NodeList, as you have already discovered. You should just return the
underlying DTMIterator with the getDTMIterator() call. For example, if
you've declared
DTMNodeList retval;
Just return
retval.getDTMIterator();
This should work fine.
