Discuss @context in Change Discovery API docs

[azaroth42]

There's no mention of @context in the API documentation. This is due, in part, to the realization of the complexity of context management across multiple specifications that are linked, but should not be tied together: IIIF/api#1571

Given the ActivityStreams focus, the only entries a context needs beyond the default AS context, is the IIIF classes for the objects. However, we need to decide (per #12 etc.) what the scope of those classes is.

The documentation is, however, incomplete without some sort of decision on this.

I think I would be fine at this stage to put an editor's note pointing to here, acknowledging that we are aware of the issue and will work on it once the spec is more mature, re. the full list of elements that we want to include. This would save some effort that would have to be re-done afterwards, partly. Would it be ok on your side?

Editorial action: Document the use of @context per other APIs, and refer to extension registry for additional contexts to use for non IIIF types.

[azaroth42]

@azaroth42 to do this for March 6 call.
