So we need to follow our own guideline of "injecting" these sorts of thing - to make the Filter evaluation context aware? Or is this a use case for Martin's might morphing power Hints? > Also, the information needed to pull this off is only available while > the filter is being parsed.

I see in your original request you talk about picking up all the namespaces available during parsing; can you show a code example about what that would do to our poor Filter api?
I am in conflict here: - I would like to preserve the separation between query model (filter) and metadata model (schema) if we possibly can; - I hate turning things into objects and having them forget all the stuff available during parsing (as in this case it comes in useful). Straight up conflict; so I guess I need to know more... my slight hope is that the parser can be "greedy" and use the namespace information it has to disambiguate the property expression during the parse...
