Subject: Re: [xacml-users] does XACML v2 allow multiple values' attribute

The problem here is indeed that SunXACML has been updated to support 2.0
POLICIES but not REQUESTS or RESPONSES. In XACML 1.1 you're allowed to
specify multiple values for the same attribute using different Attribute
elements, so this is what's currently supported. In XACML 2.0 the standard
was updated to support multiple values in the same Attribute element.

For those using SunXACML, you can specify multiple values using multiple
Attribute elements (I know, a pain). Hopefully someone will update the
request/response implementation at some point..
