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">
