IMHO, the KISS principle says that you *should* allow the full 
flexibility of XML, like you allow the full flexibility of TCP and IP. 
Layered protocol design allows code reuse *provided* that the lower 
layers are always implemented the same way.

Of course all client designers want to interoperate with jabberd, but 
there are other servers.  There are a few commercial servers, including 
the jabber.com one, there is a Java server, and so on.  In writing the 
standard we shouldn't just be documenting jabberd, we need to think 
about whether the current protocol is optimal in all respects.  Ideally 
we need to do this without breaking current implementations.  There 
should be no such breakage with the namespace compliance proposal.
