Hi,

The picture looks good!
 From my point of view such a REC normative WSA stack diagram would be 
very useful.

I have only one concern with the placement of XSD. Should we really 
stack XSD above SOAP even when keeping in mind that SOAP's syntactic XML 
representation is described using XSD. This would justify to place SOAP 
on top of XSD.

Furthermore, we should perhaps consider to split the SOAP layer into 
SOAP base and SOAP extensions like sessions etc. which could be defined 
using SOAP's header mechanisms on top of the basis.

I attached a first draft illustrating my idea.

Cheers,
  Mario
