Sure, anyone is free to use that right now. > The second is from the CDCIE chat protocol > (http://www.jfcom.mil/about/fact_cdcie.html). It's of the form: > <x xmlns='jabber:x:tstamp' tstamp="CCYY-MM-DDThh:mm:ss.sssZ/> I've never heard of that one. > For example: > <x xmlns='jabber:x:tstamp' tstamp="2008-03-10T12:43:18.002Z/> At least they are not using urn:xmpp:tstamp. However, I note that jabber:x:tstamp is improper and that general format has not been used for many years in the Jabber/XMPP community. > I favor the former as its Standards Track. I concur.
