"a" tag rel and rev

[kakalka]

I was browsing the web and somehow found this two attributes of a tag.
Can someone explain me what they are for? Or maybe give me a link to a
website (not w3c =)) which explains it nicely.

Thanks,

"This two"?

So you _don't_ want to find the _authoritative_ information on these
attributes? Just hearsay and made-up info? Try w3schools.com then.

Seriously, you don't need to know about these attributes, since they are
virtually unsupported by browsers and vaguely defined, except for
rel="stylesheet" in <link>, and any CSS tutorial should explain that part.

Install the cmSiteNavigation Toolbar extension in your Firefox,

or use SeaMonkey or Opera and visit my site or Toby's (there are a
number of folks in the NG that have progressive sites) and see the links
in action...

Seriously, you don't need to know about these [rel] attributes, since they are
virtually unsupported by browsers and vaguely defined, except for
rel="stylesheet" in <link>, and any CSS tutorial should explain that part.

It might be more truthful to say that rel attributes are virtually
unsupported by _websites_. Several more sophisticated browsers have
supported them just fine for quite a while: Opera and Mozilla variants
are two that I've used personally.

The browser support is there: it's the web authoring community that
needs to catch up.

To some extent, this is a chicken and egg problem: few people want to use
attributes that have no useful impact on anything; and few browser vendors
are willing to implement support to attributes that are not used by authors.

But basically, the browser vendors haven't even figured out how those
attributes _should_ be supported. And I don't blame them much for _this_.

What should a browser do when it encounters

<a rel="mun kiva linkkini" href="foo">bar</a>

or something similar? For a long time, there was no authoritative
_definition_ of the _meanings_ of rel (and rev) values. I would still say
so, since the current excuse for a specification of HTML semantics (HTML
4.01, that is) is particularly vague when it comes to those values. Most of
the values have little use in <a> elements, and regarding the use of <link>
elements for navigation, it was a great idea in the middle 1990s but it's a
lost cause: everyone uses <a> elements for navigation (except the misguided

I cannot see what you see as interesting in "supporting" something that is
so vaguely defined. Surely you _can_ make a browser display a rel attribute
value on mouseover or to show all links with rel="cool" as blinking, but
seriously, what is the point?
