If I have 6 capabilities but only need one
of them to perform an action the process list
does not identify the policy that is being
overridden. If I need 2 capabilities but only
have one, the one that I don't have but needed
needs to be pointed out. The capabilities
required to perform an action will not be
sent in concrete. For example, accessing
/a/file may require different capabilities
depending on the mode of /a.

You're probably right.
