I'm not convinced that it needs to.

When I originally thought about this in the context of KeySet, I
concluded that the trick was to proceed in two steps:

	1. Have the first keyset determine if the second keyset is
	   indeed a keyset.

	2. Have it then *call* the second keyset, passing to the
	   second keyset the information that is needed to do the
	   comparison.

The first keyset will remain unchanged by virtue of waiting for the
second.

I think that holding the domain creator is sufficient to get an answer 
to "is this one of yours."

Oh. I see the problem.  It cannot call the second keyset until it
knows it is not itself.

Then yes, I suppose that discrim is needed.  Yuck.

I'm just slow.
