-## Filtering responses for specific consumers

-The first mechanism is the `consumer` query parameter that allows clients to
-request items intended for a specific consumer, e.g.
-`GET /courses?consumer=rio`. When this query parameter is specified, the
-implementation should only return items required for that consumer. The
-allowed values for the query parameter are defined globally in the
-[consumer registry](#consumer-registry). This query parameter is **only**
-defined for requests that return a collection of items, e.g. `GET /courses`
-and `GET /rooms`, **not** for requests returning a single item, e.g.
-`GET /courses/{courseId}`.

 consumer for which the extra attributes are defined.

-related but separate mechanisms. It is perfectly valid to use one without the

 ## Consumer registry
 
 The following table lists which consumer keys are in use by which consumers.
 This list only shows the official and registered consumers of OEAPI that are
-part of the specification and are maintained by OEAPI. Implementations that

+register a consumer in order to use it. Implementations that wish to use this
+mechanism without registering a key should prefix their consumerkey
 with `x-`. The registered consumers are:
