<Sean> Yes, we are discussing how to update the web page
TT/Group is deprecated
Update from the AC
plh: we had a good discussion but it looked to me that we
should stay on track
pal: there was a question from timbl asking for a high level
view of the workflow for timed text to be shown in a browser

... starting in Web&TV IG
sean: worth coordinating with the IG
pal: will depend on the energy
... the web is the last link in a very long chain
sean: would be good to get everybody position down

we'll have discussion in the database

on bugs
