      Update request in example 57:

      GET ~/Products?$apply=groupby((Name),aggregate(Sales/$count with sum as SalesCount))

      Rewrite section on aggregate, last item in list on "virtual property $count": replace it with "$count, which is a shortcut for 1 with sum"

      Section 3.1 introduces $count as one of several options for aggregate expressions.

      Example 57 applies $count relative to a collection-valued navigation property, which is a different use case that is backed by the commonExpr ABNF rule to address the count of a collection (see URL spec, section 4.8). Since section 3.1 requires commonExpr to be augmented with an aggregation method, such a method must be added to the request in the example.

      The current aggregation ABNF contains a rule for $count with a path prefix, which needs to be cleaned up accordingly.
