In regard to N.4:  I think we should seriously consider adding
"scope"/"namespace"/"source" as a separate attribute, not part of the
attribute name.
That will allow for much more flexibility and interoperability in
expressing context view of enterprise data: it typically has myriad of
sources not easily grouped into our 4 predefined scopes (<subject>,
<resource>, <action>, <environment>).  Concatenation and other form of
name mangling is usually a very non-robust way for name conflict
resolution.

This separated attributes may be made part of existing "scopes", or the
concept of scope can be made extensible.

So, I would not sign on item 4)  I agree with others.

Daniel.
