Access a branch's collection content (not the collection itself) through a proxy.
Retrieve the type of data contained in the collection stored by branch; put its dictionary into dict, If there is no dictionary, put its type name into contentTypeName. The contentTypeName is set to NULL if the branch does not contain a collection; in that case, the type of the branch is returned. In all other cases, NULL is returned.
