[OGSA-AUTHZ] Start of revised charter

[David Chadwick]

Von

one final thing. There is a difference between a valid attribute and an 
authentic attribute. An authentic attribute means that it was issued by 
the issuer and hasnt been tampered with (this is an authentication type 
decision arrived at by a technique such as signature validation). A 
valid attribute on the other hand is one that can be used and is 
trusted. So for example, an authentic United Gold card is valid for 
entry into the Red Carpet Club but not into Admirals club. So the 
validation service makes the decision whether the attribute is valid or not.

David
