Are you looking at generating SNMPv1-style traps, or SNMPv2
notifications?    Will you need to specify version information
(including community/SNMPv3 user settings), or just the "payload"
of the trap?

At a minimum, you'll need to be able to handle:

   SNMPv1)   trap type (2 integers)
                      enterprise (OID)
                      + arbitrary varbind list

  SNMPv2)    trap OID
                      + arbitrary varbind list

You may wish to be able to specify uptime and (v1) agent as well,
but this is going to be the bare minimum.

A single OID is probably sufficient here (assuming v2-style)
TRAP_TYPE is redundant.
TRAP_VALUE is misleading (and either insufficient, or redundant)

That should work, yes

How would you handle string values containing a " character?

Do you have a full list of acceptable TYPE tokens?
If not, then I'd suggest using the standard SYNTAX types from
the SNMP specification, rather than inventing your own.
