XEP-0071: XHTML-IM defines a method for embedding XHTML content
within a <message> stanza so that lightweight markup can be used
to format the message contents and to create links.
Only a subset of XHTML is recommended for use with XHTML-IM.
See the full spec at 'http://xmpp.org/extensions/xep-0071.html'
for more information.
Example stanza:
<message to="user@example.com">
<body>Non-html message content.</body>
<html xmlns="http://jabber.org/protocol/xhtml-im">
<body xmlns="http://www.w3.org/1999/xhtml">
<p><b>HTML!</b></p>
</body>
</html>
</message>
Stanza Interface:
body -- The contents of the HTML body tag.
Methods:
setup -- Overrides ElementBase.setup.
get_body -- Return the HTML body contents.
set_body -- Set the HTML body contents.
del_body -- Remove the HTML body contents.
