Re: Request for egistration of character set TSCII for TAMIL language
[I prepared this yesterday, but it didn't get out because
my Win box was suddenly getting slower and slower and I had
to restart. My comments seem to be more or less parallel
to what Ned wrote.]
Hello Kuppuswamy,
I'm extremely sorry that I haven't replied to you earlier.
There are two reasons for this: I have been extremely busy during
the term here at the University, and the mailing list archive
(at http://mail.apps.ietf.org/ietf/charsets/maillist.html)
wasn't accessible for a long time. It is now accessible, but
strangely enough doesn't contain your messages.
Ned, can you check? THANKS!
(one message came back today saying that the posting limit
is too low, so the ppt attachment didn't make it through.)
Looking at your submission, it looks very good in terms of
all the data and documentation available. The main problem
is that the data isn't grouped the way we would expect it.
You sent in a .pdf file as the main registration document.
However, the main registration document should be in ASCII
only. So the main thing to do is to take some of the information
from the .pdf document, maybe with some other information
(e.g. correspondence table to Unicode) and put the ASCII
part of it directly in the registration itself.
Anything else (e.g. code chart, glyph tables,...), in particular
things that obviously cannot be put into ASCII, should remain
in .pdf (or a simliar form), but should not be entitled
"Draft Proposal for formal registration of TSCII..." or
anything similar. It's just a document describing the encoding.
Some more detailled comments below.

maybe add: As 8bit or with base64 or quoted-printable encoding

Other registrations (see e.g.
http://mail.apps.ietf.org/ietf/charsets/msg01739.html)
have included this. In your case, the mapping is more
complex, so maybe including it is not such a good idea,
but probably adding something like "please note that not
all codepoints can be converted one-to-one" or so
would help.

The intent of this section, as I understand it, is mostly
for implementers. But your text reads more like a pamphlet
trying to convince us to register. If necessary (I'm already
convinced, so I don't think it's necessary), such arguments
can be given on this mailing list.

In general, the idea is to have a small number of
people, but with more address information. Please
see other examples. The contact information is not
there to show that the proposal has wide support, but
to list somebody who can be contacted in cases of questions.
