Comments and feedback on the drafts solely addressed to the working
groups (like for instance, requests to open issues)
should instead be sent at public-qt-comments@w3.org
(archives at http://lists.w3.org/Archives/Public/www-xml-query-comments/ )
with "[FT]" at the beginning of the subject field.
Note you can't subscribe to this list, as it's just used one-way to
send comments and issues (so, it is not a discussion forum, you can
use www-ql@w3.org for that).
