I think the problem here is that XACML would need to define a
"standard" set of names like "codeSigner", "requestingUser",
"executingMachine", "delegatingUser", etc.

By using an XML attribute, XACML can define a default
"requestingUser" value, and let others be URLs that specific user
communities define.
