There is definitely value in having some amount of information at
the HTTP layer, even if it merely duplicates some info already present
in the XML-encoded header or payload. This means that existing load
balancers, proxies and firewalls have a chance of being configured
to do something potentially useful. 

I predict that in the long run, those network devices will have to
understand and deal with XML at a number of layers -- just as
switches had to learn to deal with HTTP in the first place -- 
but having the info duplicated allows for some limited amount of 
intelligent behavior by the existing network infrastructure.
