In that case, the primary can just publish pointers to the secondaries, 
and we're done.

The DKIM-like signatures have an odd model where the primary has enough 
control over its DNS to publish the validation key, and enough to give the 
secondaries signed records for their names they can publish that point 
back to that key, but not enough just to publish the secondaries' names 
directly.  I don't get it.
