A query capability can have zero-or-more shapes which reflect the
different types of resources that can be queried via the capability,
not the shape of the resulting query response.
Based on what I understand about single-subject queries so far, it
appears that we need to use shapes in two different ways in a query
1) One shape defines the query response that comes back from a query
2) Another set of shapes define the shapes of resource that you query over
Is that correct? If so, that's not what we cover in the spec.
Seems like the shape for use #1 above should be defined in the Core
spec and the shapes used in #2 should be defined by various domain

Actually, it does. Resource Shapes each exist at a URI.
