What I am saying is that if we opt by the solution that I propose, these
two flags are not needed:
If some of the DocumentSelector elements indicates that the signature has
to be enveloped
in a document, then the server will send the document with the signature in
the response
without any need to remember him...
If none of the DocumentSelector elements indicates that the signature has
to be enveloped
within any document, then the server will return the ds:Signature that it
has produced, with 
or without any enveloped document, just as it has been instructed. And this
makes unnecesary
the StandAloneSignature.
