Thanks for testing this. I went through the Xerces-C++ DOM recycling
code and it should re-use released elements. I don't see anything
broken with that code off the top of my head.

Can you try the following: in serializer.cxx, in the create()
functions (two of them), right at the beginning add this line:

doc_.reset (dom_impl_.createDocument ());

This will reset the document for every node created which should
free all the memory allocated by the document.

Can you then check if this makes any difference for the memory
consumption?
