Well, semantical equivalence  should be checked at the XML level, not
at the XMPP level. Wouldn't you otherwise have problems with plain
messages as well, since
<message><body>a</body><subject>b</subject></message> is equivalent to
<message><subject>b</subject><body>a</body></message> in XMPP (but not
in XML).

cheers,
