A SSP check is *only required* if there is an invalid signature.

No where is the SSP draft does it state that an SSP check 
must be done if the signature is valid.

If I am misreading something, please correct my interpretation,

No.  You are correct.  I have been reading into the draft specification that
the signing policy check is required if the message does not have at least
one valid signature issued on behalf of the originator address (ie by the
originator, or a parent of the originator's, domain).  However, the language
of the draft does not state this.

The recent post by Arvel Hathcock (SSP - when to perform) suggests language
that describes the requirements (or at least my understanding of them)
better.
