RE: [dita] referencing a bookmap from a map

One approach to this is to simply say that the context (“chapterness”, “partness”, or …) does not cascade when a generic topic reference is used. Where a generic topic reference is a reference from a topicref or any topicref specialization defined in mapgropup-d (mostly this just picks up mapref).

The idea is that we don't want to lose the more detailed context that is available from a topicref specialization when maps or branches of maps are referenced using generic topicrefs that contain less information.

This might or might not also be combined with a note that says that such references are discouraged and that implementations MAY, but are NOT REQUIRED to, issue warning messages in such cases.

So,

Topicref to bookmap:

Chapters in the bookmap maintain their “chapterness”

Parts in the bookmap maintain their “partness”

Chapter to map:

Top level topicrefs in the map receive “chapterness”

Part to map

Top level topicrefs in the map receive “partness”
