<BR>Debbie, Tex, thanks for catching this; in the interest of maintaining compatibility between newer and older tags, don't we need to keep the chain of preferred values <BR>
<BR>
Although I can quite see Doug's point that it's now impossible to determine what modern subtags are equivalent to the past use of 'YU,' but I still feel we need to do something to preserve compatibility . . . <BR>
<BR>
Since the comments are pretty much ignored by non-human applications, these are not the solution . . . <BR>
<BR>
(maybe the solution is in forcing the applications comments, something I suppose these applications would be loathe to do . . . ?? otherwise I have not got one; the chain preserves a partial relationship . . . )<BR>
<BR>
Thanks.<BR>
<BR>
Sincerely,<BR>
<BR>
C. E. Whitehead<BR>
