The MIB module which defines the textual conventions
used in IPsec MIBs.  This includes Internet DOI
numbers defined in RFC 2407, ISAKMP numbers defined
in RFC 2408, and IKE numbers defined in RFC 2409.

These Textual Conventions are defined in a seperate
MIB module since they are protocol numbers managed
by the IANA.  Revision control after publication
will be under the authority of the IANA.
