The following is based on draft-ietf-ipsec-isakmp-05.

1. Since my application is not Internet, I will need to define a different
DOI. IPSEC AH and IPSEC ESP are not relevant. Nevertheless, I see no reason to
unnecessarily deviate re ISAKMP. Do the ISAKMP Proposal Formats exist anywhere
- right now A.7.4 is empty.

Figure 18 does provide some information (why is Protocol # (value=1) rather
than value=3). But I can't identify what the ISAKMP Transform ID values are.
Nor do I know how to populate the 32 bit fields defined in A.6.3 (plus "Group
Identifier" seems to be undefined).

2. In places where you say "Values ... are reserved for private use." I'm
assuming it's OK to select values from this range as long as I document this
usage in my DOI. 

Do I go to IANA to get a DOI identifier ?

3. While I don't see this explicitly stated, I'm assuming I can define
additional Notify Message Types within a DOI. (The alternative would be to
define additional Payloads within the DOI.) Is any guidance available on the
best values to use should this be done ?
