Actually, I need to modify that a little bit:

   A method needs to be protected by a single permission.

   A read-only attribute needs to be protected by a single permission.

   A read-write attribute (if we have these) would be protected by two or
   three single permissions.


This doesn't change what I'm basically trying to say, though.
