Actually, that's not entirely true. First-applicable is defined
specifically as always using the order specified in the policy.

I'm not sure I understand your use of "important" and "equal". The
permit and deny overrides algorithms clearly define a precidence, and
the ordered algorithms let you specify which policies/rules get
evaluated before others. I don't think a new algorithm is needed to
solve this problem, though like I said in my last email, I may just
be simplifying things.

I don't understand this either. What do you mean there's no way to
define a new algorithm?
