In the same vein as DESCRIBE SELF would be a new verb in the protocol not the QL:

http://example/service?options


(c.f. http://example/service?query=)

By putting it here, there are no issues of "DECRIBE SELF" independent of the protocol (the API case) and also that the request is, must likely, routed to the query protocol processing code (e.g. servlets) so does not assume control of anything more than was the case for the ?query in the first place.  Is SOAP compatible (ish).
