    requests, i.e. such as ``Query(User.id, User.name)``.

    on the region and composed namespace.  The key within the cache

    itself is then constructed against the bind parameters specified

    by this query, which are usually literals defined in the 

    WHERE clause.

    the "public" method of configuring this state upon the CachingQuery.
