I understand, but where did your original statement come from?

No, there is no formal sdpecification for these, or indeed all but a
very few possible values of rel/rev in link elements.

The only definition I know of is the MS one that defines "shortcut
icon" as a seemingly singular entity.

The behaviour in Opera and Gecko seems to be a logical extension of
that that attempts to reconcile the existing practice with the
standard.

I accept that your approach is also a logical extension but it is not
one that seems to supported by actual practice.

Spot on. MS made a mistake. Defining rel="icon" would have been
simpler. It could have been worse - <body icon="favicon.ico"> or
<icon src="favicon.src"> for example.

Exactly my point: Without a formal specification that equates these two
things, there is no way that anyone can conclude that they are in fact the same
- especially when different client programs react to them differently
(including ignoring one or the other but not both).

One source often does not make an exhaustive definition. Have you searched for
other sources of information, like "www.favicon.org" (e.g.)?

And the reverse: Without a formal specification that differentates
between the two, there is no way that anyone can conclude that they
are in fact different. Lack of support for one variation can't be
taken as proof that it means something different from the other
variation, just that it isn't supported.

You still haven't demonstrated that any user agents does anything
different with them. Your original claim that one was used for the
address bar and one was used for the bookmarks is still
unsubstantiated.

So they can't be shown to be the same, and they can't be shown to be
different. So please let it die.

It does if its the only definition in existence.

The Mozilla release notes for the version that first supported icons
linked to the MSDN page.

Um, why post the URL of some spam directory? I suppose you might have
meant http://www.favicon.com but (a) that merely documents existing
browser behaviour (i.e. it's just as authorative as this thread) and
(b) it's out of date.

I am willing to let it die, but I also don't see you think I have the burden of
proof.

It's not.

Why would spam help here?

Happily.

Sorry, I can't parse that sentence. Was there meant to be a 'why' in
there? In which case the answer is because you made the original claim
and haven't offered anything to back it up.

I don't know. You're the one who posted the link to a spammy type
directory. I guess you misremembered the URL and didn't check it
before posting.
