I concur with David.  I am actually a heavy user of signing subkeys
because they allow to keep the primary key offline.


Section 10.1 says:

   Each Subkey packet MUST be followed by one Signature packet, which
   should be a subkey binding signature issued by the top level key.
   For subkeys that can issue signatures, the subkey binding signature
   MUST contain an embedded signature subpacket with a primary key
   binding signature (0x19) issued by the subkey on the top level key.

And I think this does make it a MUST.

If there should be anything else (or this is wrong, unclear, etc.), just let me know.
