Miscellaneous Namespaces

In addition to the standard Jabber namespaces that begin jabber:iq: and jabber:x:, a couple of others are used often and are worthy of our attention.

They’re both outside the jabber: namespace because they don’t originate within Jabber. The vCard format, represented by the vcard-temp namespace, is an emerging Internet standard used in many different environments, not just within Jabber. XHTML is a World Wide Web Consortium (W3C) standard that Jabber has adopted to carry rich text in messages and is represented in Jabber with the http://www.w3.org/1999/xhtml namespace.
