Michael:

At first glance the diffs look good to me too.

But I have a question: §4.3 now reads: "For a MOP value of 7, a	node
SHOULD assume that the RPI 0x23 option is enabled."  When is it ok for
a node to assume that the RPI 0x23 option is not enabled?  IOW, why is
the behavior recommended but not required?  It seems to me that the
behavior may not be consistent.

Also, please reword so that the normative action is not to "assume";
maybe something like "use 0x23"...


Thanks!

Alvaro.
