I think you could actually do it this way -  A predicate is by definition a
resource, and you could create an instance of a property class as another
resource and use that for your predicate.  Why not?  Then that edge would
have its own URI, and you could make statements about it.

Of course, if you did that for each triple you could end up with an awful
lot of resource URIs, but then you probably won't need to do it for most.

I have assumed that it is because the MT is supposed to match the M&S so far
as possible, and the M&S doesn't support it explicitly.  Anyone who actually
knows want to amplify this?
