The current draft provides information that is necessary and sufficient
for understanding and using the field.
If you think otherwise, please explain carefully, since I think there is
no other indication of technical problems with the draft.
The example provides sufficient tutorial context to make the
understanding and use concrete and accurate, as far as I can tell. And I
believe that no one else is expressing a concern, so far.
As for possible interactions with other fields, again, the instructions
in the specific are quite simple and pointed. And sufficient.
Introducing commentary about secondary issues invites readers to be
confused or to debate matters. Absent normative import -- and
especially absent demonstrated implementation or operational issues --
adding such material mostly has downsides. At best, it's simply
extraneous and ignored.

creation or use is needed, such material is suited to a broader,
systems-oriented document.
