Hi Arthur, thanks for starting this thread.

It took several days for me to connect with W3M to reflect changes in
the charter that they were reviewing. In the end, I changed the
Deliverable for a human-readable syntax to "OPTIONAL" under the
expectation that the UC&R exercise will clarify which members of the
group expect to work on such a language. Does this meet the spirit of
your proposal below?
