I would like to second Stevens comment. Those that need XML should try
to define an agreed rendering. We should probably start with the
Teragrid one as a baseline and go from there. If anyone thinks that
there are any issues that need discussing we can always collect them and
have a phone conference to sort them out. For the LDAP rendering it only
took a could of calls. Is there anyone who is motivated enough and has
enough time to lead this effort?
