RE: [saml-dev] Encoding of URI in "Alternative SAML Artifact Form at"

Thank you for your reply,but...

New question arises as to how to specify the source site identity.

You said "there is no 'specification of the source-sites identity' 
through the artifact."

Then, how does the destination site identify the source site when it 
receives HTTP get Request from a source site such as 'http://assertion_
creation_URL?..TARGET=xxxx...&ARTFACT=yyy' in Artifact Profile?
In my understanding, it  is by means of  20byte-sourceID or 
sourceLocation in  ARTIFACT data ( these data's uniqueness and semantics 
may be  effective just in the relationship between source and 
destination providers).

Isn't it correct?
