I've just taken a careful look at the bidi doc wrt the BN issue
and suggest that one of the two suggestions that follow might
help to clarify things without changing anything of importance.
Either (rewrites at the discretion of the editors, obviously)...
(1) Add an additional sentence to the end of bullet (2) of
Note that many of these characters, especially most of those
in BN, are DISALLOWED by [Tables].
(2) Add the following to the end of the introductory
paragraph of Section 2:
Passing the BIDI test is not sufficient for a label
containing applicable characters to be valid because many of
the labels that would pass this test would still be invalid
because they contain characters that are DISALLOWED
[Tables], or that must satisfy context-dependent rules that
are not met [Protocol].
Now, I am convinced that the above clarifications don't change
anything -- the relevant rules are enforced by Protocol whether
Bidi is invoked or not. But, if the inclusion of, e.g., BN, in
the Bidi-valid list has confused some of us, it is much more
likely to confuse others.
