If you drop the ContextCollection format, and adopt Atom Collection
(which is the same format as an Atom feed) you might lose a little bit
of Context-centric descriptive richness, but you will gain a lot:
1. ability to subscribe to Collections in your RSS reader (or for
developers, ability to re-use your RSS reading code)
2. a "free" publishing and update standard
3. a "free" categorization scheme
I attach a sample Atom Publishing Protocol (APP) service document for
an OWS Context Collection (file: context_service_document.xml) and a
sample Collection document (file: context_feed.xml).
What do you think of this idea?

There has been little talk about ContextCollection which is a simple
but effective way to list Context documents. It would be a useful
format to be returned from a Catalog query.
