Look the other way round: XMPP was supposed to use XML. Some first
implementation did namespaces and some other bit wrong because of
misunderstanding. So now we have some prefix usage forbidden, which
makes using some existing XML implementations harder (you cannot use
ElementTree library to properly serialize XMPP stanza -- it will use
other prefixes, than XMPP expects). AFAIR there were other similar
problems with XMPP XML usage, some where fixed in favour of XML standard
(now most software will break connection on non-well formed, because of
wrong character encoding, XML), others, like the namespace usage, by
limiting XML in XMPP.
IMHO XMPP should become more XML compatible and not less. Both existing
XML parsers and serializers should be usable for XMPP. If something has
to be changed in the XMPP specification then it should be removing the
incompatibilities and not adding more. Now CDATA is perfectly legal and
that is OK -- why forcing users to create their own XML serialization
routines by another XMPP limitation?
