The Identifier property is useful for audit and management in the  
backend.  I believe this should remain in the specification and should  
remain a normative section, agreeing with Thomas note in the chat. It  
was added based on requirements from WG members.

Thomas mentioned in the chat the means to obtain unique values, e.g.  
large random number, serial number + DNS  etc, but I think this can be  
out of scope of the spec.

Currently the specification states
Each widget signature MUST contain a dsp:Identifier signature  
properties element compliant with XML Signature Properties [XMLDSIG- 
Properties] and this specification.

We can add, "A signer MUST place the dsp:Identifier signature property  
into the signature when generating the signature." if necessary.
