I think the interaction between annotation changes (among them
workflow state changes) and the catalog is not yet well
understood.

There was a discussion some months ago about this, mainly
between Jim and me. I proposed something like
a "DependentObjectModifiedEvent(dependentObject, primaryObject)",
deriving from "ObjectModifiedEvent", as an efficient
way to communicate with the catalog.

The catalog could use "primaryObject" to determine the
document id but "dependentObject" to determine a more narrow
set of indexes that need to be updated.

Jim proposed a set of alternative approaches.
