However, the specification as now written incorporates all or
UTS#51, a long (very long if the required supporting tables are

IETF have described as a Unicode-based picture language of very
high complexity that is necessary to understand.
Discussion of this draft was conducted on the ietf-822 mailing list for
two months, last September and October. Early in October, the spec
added the UTS#51 reference.
You participated in the ietf-822 discussion but did not raise any of the
concerns you are now offering as being critical. Nor did anyone else.
What has changed?
Above you make a claim to controversy about this specification. I've
looked and am not finding it. Please provide a reference the rest of us
can use to review it.
For all of the concerns you insist are fatal to the current
specification, you have yet to offer an alternative that can be compared
against it.
Suggestions for modifying the specification, to add various constraints
or commentary surrounding the use of UTS#51 pertain to that external
specification and not to its use here.
That is, you are pressing for having an IETF specification contain
tutorial material about another standard body's work or to declare some
constraint on the use of that work -- though we can't yet tell what
constraint you would find satisfactory, in spite of your multiple,
extended postings here.
There is a simple reality that that external work has been around for
awhile and has field experience. To the extent that there are nuances,
complexities, or the like, that area of work has been developing it.
The IETF hasn't and should not pretend to exercise expertise about it.
Then there is the small matter that this specification is intended as
Experimental. That's supposed to allow room for gaining experience.
If the horrors you fear do appear, we'll find out, won't we?
