his is interesting, and speculative, future work. However, and not
distracting from the original specific issue:

I don't see how the issue of how/whether to point to a portion of an xml
resource which happens to be in RNG, has *any* bearing on the issue of
what media type to use when RNG is served as a stand-alone document,
which is by far the typical case at the moment. There is no dependency
there.

So, now I am asking them to consider it. Will you convey this request to
them, or do I need to convey it by a more formal mechanism?

I don't follow your last point there.
