Re: New issue: IMG section of HTML5 draft contradicts WCAG 1 & WCAG 2 (draft)

I would have to agree with you that it would make more errors possible.
noalt, or wathever the chosen solution for the situation when an alt text is
not available would be used in a similar way to the font tag with the
wysiwyg meta tag (I know that is also debated)

The idea here is that when used in conjunction with a meta generator tag,
that noalt would not be ambiguous. I would agree that does not precludes bad
copy paste by authors and that those errors must be accounted for. (They
could also copy paste the meta, which would leave us nowhere good)

if alt is not required in the case when it is not available, would it be
possible to force the inclusion of a meta tag that basically says that the
page is generated and that some @alt are not available ?  This would at
least give some information to user agents. It does complicate everything
else though ... I am not sure this is a good idea

@noaltavailable maybe ? it is certainly less confusing... but not a lot

Tough decision indeed....
