completion-in-region-function accepts COLLECTION, right? That's usually 
the completion table. From there, you can access the table's metadata 
and see its category or etc (if you control the table, it could contain 
some additional distinctions).
So your custom completion-in-region-function could look up metadata and 
dispatch to one of the two specific interfaces, couldn't it?
