Description

Specific queries to explore contents of a scope within the high-level model.

This is an application of the QueryResolver facility, and used heavily to provide the various search and exploration functions on the session API. It is implemented by accessing a SessionService, which resolves the queries by iteration on the PlacementIndex behind the scenes.
