For the most of it, <link> does not help accessibility. It makes the use
of a page more comfortable on some browsers, and may affect indexing
robots. For accessibility, use links (i.e., <a href>), not <link>.

Studying the behavior of Mozilla, Opera, and other advancing browsers is
the practical approach.

Regarding the topic of this discussion list, I think we can mostly say
just that rel attribute values should have been standardized years ago
and it would still help to do that now, but that there's probably no work
in progress, since the discussion revolves around XLinks and other
theoretical constructions.

Because there is no specification, just vague notes

Mostly not.

Apart from rel="stylesheet", they have rather marginal use. You still need
to have explicit links, for the vast majority who uses <link>-challenged
browsers, so what's the point?

Beats me. I'm afraid the spec is _intentionally_ vague. But I've used them
to specify sections and subsections _inside a document_. It's duplication
of course, since a normal ToC is needed too.
