 Mark,
 I'm not sure what you mean by "web architecture", because I 
thought we have yet to see that. 8-)
 Anyway, from SOAP-centric point of view, a transport binding 
specifies means of getting SOAP messages from one node to 
another.
 I think that your proposal (of making the Body optional) should 
come from a use case independent of any particular protocol 
binding, not from some unusual but possible use of GET method in 
HTTP.
 Do you have any use case for Body-less messages that is 
independent of HTTP?
 Best regards,

                   Jacek Kopecky
