Hi Jean-Jacques,

Given that WSDL may be used with more than just SOAP bindings,
IMHO it should be possible to describe in WSDL the existence
of header blocks (i.e., contextual information) independent
of SOAP.

When the contextual item is bound to a SOAP header block,
however, I would be ok with requiring that to indicate a SOAP
module URI.

However, as others have pointed out, this doesn't prevent
a SOAP headerblock which doesn't have a module URI popping
up. We can however do it right at a WSDL level.

Sanjiva.
