Subject: [Dime] Classification of Erorr Codes in RFC3588

What is the rationale behind classifying DIAMETER_COMMAND_UNSUPPORTED and
DIAMETER_INVALID_AVP_BITS as protocol errors? They seem to be end-to-end
issues fitting more to Permanent Failures category.

Considering Protocol Errors SHOULD be treated on a per-hop bases, are we
expecting a relay agent to be aware of every supported command by each
peer/application to be able to generate DIAMETER_COMMAND_UNSUPPORTED? Or,
are we expecting all intermediares to look to all AVPs in a message and
check the validity of AVP header bits for DIAMETER_INVALID_AVP_BITS case?

    Thanks,
    Tolga
