So these clients are buggy. AFAIK JID containing only the domain
is 100% valid. And the clients should be fixed.

I am very worried about most jabber implemetations. I don't know if
there is any which properly follows jabber and XML standards. This is 
very bad. 

I write two transports for jabber and a big part of code contains
various workarounds for clients' bugs. For the component I just write 
I decided to use one of available full-fetured, namespace-enabled XML
parser (PXP). And to make it work with jabberd or psi I had to write
some ugly workarounds, as those programs doesn't seem to support
namespace prefixes (other than those commonly used in jabber, like
"stream:") :-(
