Title: [xacml] Principals in Applicability - was RE: [xacml] Version 0.7
Hal -
I had promoted the term "applicability", not because I felt it was
preferable to your proposed term: "target", but because we needed a
term for this concept, and I did not understand that "target" was
intended to serve exactly this purpose. Personally, I would be happy to
switch to "target".
I
agree with the points you make in this message.
I was,
however, thinking that (to pick up your very final point) XML documents, to
which these policies control access, would have fully qualified namespaces to
identify their type. Then the policy (even if it is attached) would
"target" that namespace. This approach, of course, means that
the policy applies uniformly to all instances of the type. We should
probably debate the use of the reserved word
"this".
All
the best. Tim.
