Introduce path segment /$x for cross-joins on entity-container level
--------------------------------------------------------------------

                 Key: ODATA-434
                 URL: http://tools.oasis-open.org/issues/browse/ODATA-434
             Project: OASIS Open Data Protocol (OData) TC
          Issue Type: Bug
          Components: OData ABNF Construction Rules, OData URL Conventions 
    Affects Versions: V4.0_CSD01
         Environment: [Proposed]
            Reporter: Ralf Handl
             Fix For: V4.0_CSD02


The current URL convention allows querying the cross-join of entity sets via requests targeting the entity container.

This leads to potential name clashes:

	GET ~/Foo.Fred.Waldo

can be a query targeting the entity container Waldo in schema Foo.Fred, or a query targeting entity set Waldo in container Fred of schema Foo.

This clash can be avoided by appending a path segment /$x to the entity container name, similar to the path segment /$all that we use to address the union of all entities in a container.
