  You can do through xmlMemSetup()
    http://xmlsoft.org/html/gnome-xml-xmlmemory.html#XMLMEMSETUP

  you mean using you own message callback, sure change the 
  error, warning and fatalError either in your SAX block or directly
  in the xmlDefaultSAXHandler block.

  Okay libxml doesn't use glist

  That I understand.

  Okay should not be too hard to doublecheck.

  Correspond more or less to SML an XML simplified version developped
by some people using XML for purely data centric use:
   http://www.xml.com/pub/1999/11/sml/
 but SML is even smaller than your subset (or was supposed to, I didn't
heard much about it lately),
  I have no problem with GMarkup, I understand where you come from
and the reasons. As long as people are not pointed to GMarkup as being
a generic XML parser, it makes sense.
