Hi, Steven, and thanks for the response. > I have changed them all to: > > It MUST be set to 0 if the router is not capable of doing FOO, > otherwise it SHOULD be set to 4 but MAY be set to any value from 1 to > 7 to indicate a non-default priority.

I'd prefer lowercase "may", rather than the 2119 key word -- the SHOULD has the 2119 language covered -- but, in any case, this resolves the DISCUSS point nicely.

I'll respond to Markus's message on this point. Your responses to my other comments are good, and thanks for addressing them. Barry
