A complicating factor to this though is that it would need to be done
*after* all of the other content merges. That implies some sort of
dependancy graph, *bleah*. I've never been terribly fond of the idea of
catalogs as top-level instance space objects (i.e., peers to the content
they catalog), and things like this are one of the reasons why.

In any case it might be good enough for an object to be able to say
"merge me last". Other toolsy and servicey sorts of objects that depend
on content (like a workflow state repository) might want to do so as
well. As long as the state of the tools doesn't depend on each other,
then it's ok. That last sentence is making me a little ill, however ;^)
