Looks interesting. A few questions after reading the spec.

What's the thinking behind must- vs. may-bind? I gather this isn't altering
the result at all, but just telling the server its options when returning
the results to the client. Is that right? I can see the utility of bind vs
no-bind but why is it necessary/desirable to distinguish between must and

Is it allowable to pass an empty answer KB pattern if a query premise is
included? seem this might be useful for dumb clients that want to bounce
their data + queries off of a query server.
