It would be nice to be able to group related Link parameters (particularly in docs — I'm not sure, yet, what use a client lib might make of it.)

I have two clear cases from Django Filter in mind.

• Where we allow a lookup type (exact, icontains and so on) together with the lookup value. Here you cannot submit just the lookup type.
• In a to/from range filter, where you can submit one or both values to act as lower/upper bounds.

In both cases it would be nice to communicate the relationship, with a description or such.

Just opening this to raise it currently. Details lacking.
