ACK.  The only thing I hadn't seen before is the * defined in

Please test it:  <news://*>  With my excuse
for a real newsreader (Mozilla 3) it has the same effect as
<news://> or <news://>:  It
"closes" (where I read, and
"opens" showing my subscribed SC newsgroups.

With that syntax <news://> would be invalid.
How about:

    newsURL     = "news:" ( group / article / news-server )
    group       = [ news-server "/" ] newsgroup-name
    article     = [ news-server "/" ] message-id
    news-server = "//" server [ "/" / "/*" ]

A message-id starting with "//" could be a problem.  How's
that supposed to work, more %2F hacks as for the ftp URLs ?

And newsgroup-name needs some proper syntax, anything where
"@" is impossible and not starting with "//" goes.

I've never seen it in a newsURL.  IMHO it's unnecessary to
mention it.  Actually I know only five common forms:

news:message-id         ; Usenet article, use your own server
news:newsgroup-name     ; Usenet newsgroup, use your own server
news://server           ; some special server (usually public)
news://server/group            ; group on the special server
news://server/message-id       ; article on the special server

Isn't that covered by 2396bis ?  Just don't mention it at all.
Paul's draft is about the scheme, not about the finer points
of 2396bis or SASL w.r.t. nntp.

"and possibly a userinfo".  No details, it's all in 3.2.1 of

Delete this.  It has nothing to do with the scheme, and I've
never seen a <news://ogin:sword@host> in the wild.

ACK.  Actually my good old Mozilla 3 has "default servers" in
its configuration files, and uses this server if needed.  OTOH
if whatever server is already "open", then this is the default
server for unspecific news-URLs.

No.  It's used to refer to articles or newsgroups on _specific_
servers.  And not necessarily Usenet servers, any news server.

Actually it's a bad idea for Usenet articles and newsgroups,
because it works only for users of the specified news server.

My good old Mozilla 3 does not support this scheme.  They made
good stuff at Netscape before they lost their "war" against the
evil empire.

BTW, there was already a draft for news:, the author should be
mentioned in the credits:
