I still desire a "revocation target" subpacket to identify the
specific signature being revoked...

In the immortal words of Rod Serling, submitted for your approval:

.head 4 Revocation Target

.block blank
(1 octet PK algorithm,
 1 octet hash algorithm,
 N octets hash)

This subpacket identifies a specific target signature that a revocation
signature revokes. This provides explicit designation of a revocation. All
arguments are an identifier of that signature.

The N octets of hash data MUST be the size of the hash of the signature. For
example, a target signature with a SHA-1 hash MUST have 20 octets of hash
data.
