In order to accurately and interoperably compare public identifiers,

Hum, right. Basically all public entry point using Public ID should be
patched to check this and if needed a new string should be allocated.
That would need a new function for this, and a few more line in all those
functions ... Not very hard but admitedly boring :-)

If you agree, I could try to produce a patch to that effect.

  Sure, that would be welcome. The public entry points are in
include/libxml/catalog.h then patching them to do something like

static xmlChar *
xmlCatalogNormalizePublic(const xmlChar *pubid) {
   return(NULL if not needed or copy otherwise)

foo(const xmlChar *pubid) {
   xmlChar *normid;

   normid = xmlCatalogNormalizePublic(pubid);
   if (normid != NULL) pubid = normid;


   if (normid != NULL) xmlFree(normid);

  would be greatly appreciated :-)
