I suspect you're smoking better quality drugs than I can get locally. 
Please read through http://en.wikipedia.org/wiki/OSI_model .

Introducing XML at the 'network layer' has a huge number of complications, 
as XML is not a strictly-ordered protocol. It means that every device 
receiving such a packet must run an XML parser, in order to find out where 
in the packet the routing information actually is.  This differs from a 
'real' network layer protocol such as IP, where the routing information is 
located at fixed offsets within the packet, and thus, is comparitively 
easy to put into silicon.

Within the context of Jabber, XML is simply a data format used by an 
Application Layer protcol formerly named 'XMPP'.
