RFC 1905 also uses the phrase "request-response transaction" on page
8. I am not sure why this text is unclear or what needs to be

I have changed "SNMP timers" to "SNMP retransmission timers" in case
that was the problem. If you are concerned about the verb, please note
that other protocols such as OSPF version 2 (RFC 2328) also talk about
timers that fire.

I changed "accepting" to "accepting and generating".

I have replaced "confirmed requests" with "confirmed operations" as

I replaced "delivered to" with "queued for delivery to" to make this
subtle point clearer. With some additional editoral changes, the
revised paragraph becomes:

   With a confirmed SNMP operation, the receiving SNMP engine
   acknowledges that the data was actually received.  Depending on the
   SNMP protocol operation, a confirmation may indicate that further
   processing was done.  For example, the response to an inform-request
   protocol operation indicates to the notification originator that the
   notification passed the transport, the security model and that it was
   queued for delivery to the notification receiver application.
   Similarily, the response to a set-request indicates that the data
   passed the transport, the security model and that the write request
   was actually processed by the command responder.

No problem with this suggested change.

Due to some offline comments from an implementor, I also added a
clarification that the TCP connection SHOULD be closed when the
receiver looses framing (e.g. due to ASN.1 parse errors).

I will submit a new ID with these changes in place.
