[OGSA-AUTHZ] VO SAML Attribute Profile

Hi, following (with an embarassing delay) Tom Scavo's mail on defining a SAML profile for VOMS attribute, I'm posting a document Krzysztof Benedyczak and I was editing with initial thoughts on the matter. I'm not uploading it to gridforge until it's more complete than it is now. If the issue raise interest and we manage to agree on a document, we may ask Blair and DavidG about a possible recommendification, though I think that not being in the current charter make it difficult. Let's see, the discussion is anyway usefull. I profit to wish everybody a nice holiday. Valerio
