Verification Points
The receiving entity MUST select a single transform for each protocol
in a proposal or reject the entire proposal.

IDENTITY PROTECTION EXCHANGE
# Initiator(TN) Direction Responder(NUT)
(1) HDR; SA ========> <-----Multiple invalid transform payloads
(2) X <======== HDR; SA <-----Must not transmit
Judgement (Check *1)
1. Send the first message from TN
In the first message (1), the initiator generates a proposal it
considers adequate to protect traffic for the given situation. The
Security Association, Proposal, and Transform payloads are included
in the Security Association payload (for notation purposes).
2. Receive the second message from NUT
In the second message (2), the responder indicates the protection
suite it has accepted with the Security Association, Proposal, and
Transform payloads.
The first message must not be accepted. And the second message(2) must
not be returned.

The Transform payload provides the initiating entity with the
capability to present to the responding entity multiple mechanisms,
or transforms, for a given protocol. The Proposal payload identifies
a Protocol for which services and mechanisms are being negotiated.
The Transform payload allows the initiating entity to present several
possible supported transforms for that proposed protocol. There may
be several transforms associated with a specific Proposal payload
each identified in a separate Transform payload. The multiple
transforms MUST be presented with monotonically increasing numbers in
the initiator's preference order. The receiving entity MUST select a
single transform for each protocol in a proposal or reject the entire
proposal. The use of the Transform number in multiple Transform
payloads provides a second level OR operation, i.e. Transform 1 OR
Transform 2 OR Transform 3. Example 1 below shows two possible
transforms for ESP and a single transform for AH. Example 2 below
shows one transform for AH AND one transform for ESP OR two
transforms for ESP alone. Note that the Next Payload field of the
Transform payload points to another Transform payload or 0. The
Proposal payload delineates the different proposals.
