Subject: Visio diagrams for assertion
All, Attached are a set of diagrams for the current assertion schema. There is a visio file and for the visio impared two sets of HTML/GIF versions. The protocol diagrams will follow. The difference between the 2 HTML editions is that one has annotation by Phill and the other does not. I discovered a couple of odd things about the schema while making the diagrams. Visio-able people can turn the annotation on and off as layers. The first seven drawings consist of the actual schema as it is today. The last three are two possible modifications. The first uses substitution groups to avoid the use of xsiType= at the top level. The second shows an alternative structure which differenetiates the assertion container from the statement made within. This proposal allows Prateek's desire to have 'content ignorant' processors be able to work on the wrapper of an assertion without bothering themselves with the semantics of the statements. It also allows the addition of multi-statement and multi-assertion containers at a later date that would be capable of containing SAMLv1.0 statements, the current structure is inflexible in that regard. The second proposal could be implemented without substitution groups. This is a Zip file 'cos there are a lot of moving parts. Phill Phillip Hallam-Baker FBCS C.Eng.
