Subject: [xacml] Re: Observation on J2SE context proposal
OK. I agree to that <NameIdentifier> should be a special element for
<Principal>.
So it would be nice that XACML Context reflects that notion.

I think the NameIdentifier needs to be a special attribute
because each Principal must have exactly one. Other attributes
are all optional, and multiple instances do not cause problems.
The NameIdentifier could become an xml attribute of the Principal
element, but we would then have to deal with Format, ds:KeyInfo,
etc.
