The semantic of 'next' is 'subsequent page' not 'drill down' which you
seem to use it for.

No, not necessarily. But a hint is allways good.

This is a problem (see 'next' above) since the specific intention of
'Loads only the competition of type "competition owner"' is not
communicated ny the link rel.

use application/xml then all the client can assume is 'process this as
