IMHO, you should make some advertising for this list on the xml.apache.org site.
Because if you had never sent a mail to firstname.lastname@example.org
, I would have never known this community existed.
P.S. : by the way, Martin Stricker said :
" OTOH it's quite easy to move stuff from one project's repository to common and get it at build time"
Wath does OTOH means ?
