Re: [syndication] Re: LINK support in Mozilla 0.95

[Mark Nottingham <mnot@mnot.net>]

I think the methods you outline are certainly doable (although having
a separate rel='...' attribute for each version of a format isn't
really in the spirit of things). Probably the simplest way to do this
might be to put all of the links in the document itself, as

  <link rel="alternate" type="application/rss+xml" href="..." title="..."/>
  <link rel="alternate" type="application/newsml" href=..." title="..."/>
  ...

'alternate' is already defined, and seems like a good fit; an
argument could also be made for a separate 'syndication'.

This would require a MIME type to be defined for each feed format.
Not a bad thing, IMHO. This *doesn't* mean that those files would
have to be served with that type (again, not such a bad thing, but
difficult for some to do).

Versioning of a particular format (e.g., RSS) would either be the
responsibility of the aggregator, or if somebody REALLY wanted to do
it, we could normalise a MIME attribute; e.g.,
  <link rel="alternate" type="application/rss+xml;version=0.91"
   href="..." title="..."/>
and so forth.

Comments? If we can get some consensus here, we can probably get this
supported in Mozilla relatively easily...
