Validation and adherence to the HTML spec are not exactly the same
thing. All spec-adherent websites are valid, but not all valid sites
are spec-adherent. So full adherence to the spec is more work to ask
of publishers than simple validation. Ironically, I think the HTML
validator actually encourages poor use of the alt attribute because
it returns an error on missing alt attributes, but doesn't make any
mention that alt should be empty for non-content images. So
publishers who leave out alt on non-content images see this error and
end up adding alt attributes with exactly the kind of "red ball"
values the HTML spec discourages.
I completely agree such publishers should be encouraged to stop doing
this; I just doubt whether such encouragement should come from the
microformats community. I see our goal as a bit more specific than
general encouragement of better HTML: making better HTML publishing
more appealing by establishing practical benefits. And I think the
best way to do this is to focus on areas where better HTML results in
maximum practical benefits with minimum cost to publishers.
In this case specifically, I suspect the best way to accomplish that
goal would not be to encourage everyone publishing non-content alt
attributes to change, but rather to encourage everyone publishing
content in alt attributes to insert such content as more accessible
text, and use style sheets to apply more stylized images, which I
think is what Ben was suggesting (see ). This solution, I think,
makes better HTML more useful without making microformats any more
difficult to publish for those who aren't up to spec.
