  Well so far there is no xmlListProp() function. People, me included
simply walk the node->properties list, however this is not always sufficient
since some properties may be inherited from the DTD and in this case are
not listed on node->properties.
  Libxml2 is in an API freeze mode at the moment, but I don't think
there would be any resistance to adding such an entry point. If someone
provides a correct patch to add this I would certainly integrate it,
the only tricky part is to get the element definition from the DTD
if available and add defaulted attribute if not already present in the
node->properties list.
