Indeed. This is an area that I found required a fair amount of work on the
version of HaXML I was playing with, some time ago.
The change log at the end of:
has some clues to what I had to do. Notably:
-- Revision 1.12 2004/06/04 21:59:13 graham
-- Wortk-in-progress: creating intermediate filter to handle parameter
-- entity replacement. Separated common features from parse module.

-- to dtect and substitute PEs. The result is a modifed token sequence
