If the matching is left to an arbitrary, server defined algorithm, we lose interop since a client implementation may make assumptions on what may be allowed in the redirect_uri at one AS and then not be able to work with another AS that is more restrictive. As this is a security feature, I'd like to hear the options from the security oriented participants with experience here. Allen / Brian?
