      We often have requests to support queries that span entitysets. Where navigation properties exist between the entitysets these provide a natural and convenient mechanism for building queries that span entitysets. However, where navigation properties are not present a way is needed to build such cross-entity spanning queries.

      In the context of looking at aggregation we came up with a solution for doing this by considering the entitycontainer as the cross-product of the contained entitysets. You could then $expand the entitysets you wanted to join, and add a filter to specify the equivalent of the join condition. This seemed generally useful beyond just the scope of aggregation.
