Subject: RE: [xacml-users] Reg. <ResourceContent>

There is no such assumption.  The idea is that when resource is an XML
document, it can contain (maybe partially) the context.  Context is
notional. Even if it is a representation of a resource, it may include
any attributes.

Personally, I think AttribtueDesignators should not have a kind either,
as they have no other meaning other then to group attributes in the
context to some traditional categories.  Maybe I should suggest for 3.0
to reconsider that and make attribute kind an extensible identifier for
association with arbitrary data sources.

Hmm - interesting...

Section 6.4 states:

"The <ResourceContent> element is a notional placeholder for the
content of the resource.  If an XACML policy references the contents
of the resource by means of an <AttributeSelector> element, then the
<ResourceContent> element MUST be included in the RequestContextPath

The key phrase that struck me was - "notional placeholder for the
content of the resource" - hence my assumption that <ResourceContent>
can be used only for xml content representation of resources.
