If we think of a mapref as being parallel
to a conref (basically a shorthand for "pull the target hierarchy
into this point in this hierarchy, but push reltables to the end because
they're not allowed within a hierarchy") then we should discard the
chapterness - just like we discard <step>ness when we conref from
a <li>.
Otherwise we allow chapters to nest,
and break any bookmap processors that are expecting DTD-validated content.

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”
