I do NOT believe that this thread should be discussed on the Unicode
List. I am responding to it only because Dean has let loose another
brace of hares. Let us reign them in, and kill this thread now.

No greater hames have we ever made than encoding Mongolian without a
proper implementation model. But go ahead, Dean, engage in yet
another flight of fancy.

We are not going to use a "dynamic" model to encode Cuneiform. This
has been decided.
Variation selectors are not the joyous answer to Dean's prayers.
Variation selectors are, in fact, a vexatious and nasty form of
pseudo-coding which pretty much sucks, except maybe for
mathematicians.

Not in a month of leap years.

There is every technical reason for refusing a "dynamic" model for
Unicode. It is a bad idea. This has been explained, politely and not
so politely, to Dean, who persists in annoying everyone by waving his
hands and ignoring the opinions both of authors of the Unicode
Standard and of other cuneiformists.
The "dynamic" is inferior to the "static" model we have chosen. We
chose the model years ago, for good reason, not least the ease of
timely and simple font provision. The static model we have chosen is
good enough for 70,000 Han characters, and the dynamic model is not
good enough for any of them. The same shall apply for Cuneiform.
[More blather deleted]
Dean wanted to use control characters, then ligators, and now
variation selectors in order to glue characters together to make
other characters. From recent discussion on the Cuneiform list:

To represent the crossed ligature we use
U+12212 CUNEIFORM SIGN LU2 CROSSING LU2.
To represent the opposed ligature we use
U+12214 CUNEIFORM SIGN LU2 OPPOSING LU2.
No gluing. No splicing. No alternate format characters. No ligator
characters. And no variation selectors.

Dean. Perhaps you should consider revising your signature. Because
your continued harping on this matter is not in the least bit
"respectful". Rather, you are endeavouring, fruitlessly, to upset and
overturn the consensus which we have for encoding Cuneiform, ignoring
the fact that whenever you ask us to take time to respond to you, you
are really asking us to waste our time defending good work against
bad. The experts have given their opinions, for a month now since you
re-introduced the "modifier" idea on 2003-12-17. If you want to be
"respectful" you will accept those opinions.
Because we are not going to use a "dynamic" model to encode Cuneiform.
Now have DONE.
