Subject: Re: [xacml-users] does XACML v2 allow multiple values' attribute
Hi Hao,
The syntax "&roles;[role-name]" is simply used for shortening the full URI
for the role identifier. From the spec:
<!ENTITY roles "urn:example:role-values:">
So "&roles;[role-name]" is equivalent to
"urn:example:role-values:[role-name".
Section 1.1 of the RBAC profile defines these notations. They are mainly
for readability in the specification.
Regards,
Craig

I am not sure if XACML request CTX allows to have function defined there.
