Subject: RE: [regrep] FW: [Ebxmlrr-tech] Re: ebXML Registry --- can work as distributed registries?

We do not have a formal response process for questions like this.  We
all work to educate others about the specs, and if someone runs into a
question they don't know the answer for, or don't feel comfortable
answering, they generally enlist the help of one of the other TC
members.  Farrukh gave a very thorough response, pointed out the age of
the article, and addressed all the issues in a very clear fashion
(thanks Farrukh).  Comments that come into the Regrep Comments list are
responded to and posted to the regrep list as well.

The broader issue you are asking about I believe is can/should we have
coordinated responses, etc.  I agree with your suggestion for using the
FAQs as a good place to post questions and answers - we have a couple up
right now, but should probably work on a couple more in the near future.
As before, if anyone has a question and a suggested answer, please post
to the regrep list, we will discuss in email, and when agreed to, I will
have it posted to the website (OASIS has to do the posting in this

Additionally, OASIS can assist any of the TCs with publicity on the
OASIS site, Cover pages, etc.

I personally am fine with Farrukh's excellent response, and believe that
it is simply a misunderstanding on the part of the poster that arose
from the article being over 2 years old.
