Hi all,

I apologize for sending previous message without any response text in it. Pleas

It does not. Probably we should better explain in the text what the intended
use of the interface.

When a new policy or a set of policies are specified for a resource name, first
replace_policy() is invoked. The operation is supposed to have the following
affect:

1. Any existing associations of the given resource name with any policy or
policies names are removed.
2. The given policy name is associated with the given resource name.

Then, if more than one policy name is to be associated with the resource,
add_policy() is invoked as many times as many new policies (besides the first
one) should be associated with this resource.

The text does not mandate any semantics of relationships between various
policies associated with the same resource name in a given policy evaluator.


I hope the explanation was clear. If anybody from submitters or supporters fill
like adding comments to our discussion, they are always welcome to jump in.

Thanks for your questions.
