resending: updated timed-text document

(a faulty address in the last mailing.  apologies for the redundancy.)

======
Everyone:

An updated timed-text requirements document is now available at

http://www.w3.org/AudioVideo/timetext.html

I've reorgainized it, included a summary of why we need a standardized timed-text format and made changes and additions to the requirements based on recent comments by various list members.  If I've missed something, or if you have something else to add, please let me know.

Thanks!
