This is an alternative form of reference
for news articles, specifically to
be used with NNTP servers, and particularly
those incomplete server implementations
which do not allow retrieval by message
identifier. In all otehr cases the
"news" scheme should be used.
The news server name, newsgroup name,
and index number of an article within
the newsgroup on that particular
server are given.
Note1.
This form of URL is not of global
accessiablity, as typically NNTP
servers only allow access from local
clients. This form or URL should
not be quoted outside this local
area. It should not be used within
news articles for wider circulation
than the one server. This is a local
identifier for a resourse which is
often available globally, and so
is not recommended excpet in the
case in which incomplete NNTP implementations
on the local server force its adoption.
