>bugzilla numbers

I actually asked for issue numbers or bug numbers.  If all the items are already WG issues then there is no need to give the bug numbers since this information is easily available.  I was only looking for numbers for unescalated bugs, if any.

Dear All:

I propose we move the gathering of issues to be flagged as unresolved for HTML LC to the HTML-A11Y list.

Rich, can you please forward this to HTML-A11Y? I don't feel right doing so on your behalf.
Note also, please, that Paul has requested additional specificity, e.g.
bugzilla numbers, asthose may be available.
