Yes, that is why I was trying to understand your second suggestion which
was not answered by your email. I think you are making some assumptions
with respect to scoping of the assertions which I am trying to uncover. 

Could you clarify in which situations you envision RMD side assertions
needs to communicate RMS in a separate protocol element and whether that
protocol element must be defined by this specification? Typically, the
endpoint would already have the assertion associated (WSDL/Attachment)
which is already available. The scope is the endpoint. I presume you are
thinking of different scoping requirement here. 

Thanks,
