I think that this entire section belongs in the Extended Protocol ID, not
this
one.  I made a similar comment to Laura.  This way, we can agree on a
behaviour
and only describe it once.  The individual extensions can then talk about
specific behaviours and not general ones.

What the Extended Protocol ID says is:
"If an SNMP entity receives an extended protocol feature it does not
   understand, it MUST follow the unknown PDU response mechanism as
   defined in [RFC2262] section 4.2.2.1"
