XMPP is used for many things other than sending human-readable IMs. One
prominent example is Jingle, an extension for managing voice, video, and
other multimedia sessions that is used in the Google Talk service and
several open-source XMPP clients. Such extensions are not forced into
the message body, instead they are XML-structured payloads that are
often placed inside the XMPP <iq/> element rather than the <message/>
element. You can see examples here:

http://xmpp.org/extensions/xep-0167.html#example-1

http://xmpp.org/extensions/xep-0234.html#example-1

If you're exchanging things like IP addresses and file names, you really
might want to encrypt that end-to-end so snoops in the middle can't
learn things that are none of their business.

Ideally, a future version of OTR would have a mode that enables people
to send this kind of information, instead of just XML character data
like the "foo" in <message><body>foo</body></message>.
