I'd agree.  I'd also note that there has been some controversy relating to
usage of the 'M'andatory bit.  For example, my understanding is that some
implementations return terminal "Missing AVP" errors in response to
missing AVPs classified as optional in the Diameter specifications.
This is a troubling development, since could affect interoperability at
the most basic level.
