11.5.4.1 Invoking an Action: Location header for 201 Created responses

Section "11.5.4.1 Invoking an Action" specifies that actions creating entities respond with 201 Created. Nothing is mentioned about the location header.

For consistency with section "11.4.2 Create an Entity" actions that create and return a single entity MUST also send a Location header to allow referencing the newly created entity with a content-id within batch requests.

Section "11.7.3.1 Referencing New Entities in a Change Set" has to be reformulated to also cover new entities created by actions.
