I agree the best approach is to have meaningful link text, but sadly the W3C
decided to relegate this to AAA in WCAG 2.0. We all had an opportunity to
argue against this during the protracted process of getting WCAG 2.0
introduced, but in the end although some of us argued against it, we weren't
vocal enough and didn't have the numbers or strength to win the day.

However, on a wider point - I am becoming increasingly concerned by the
tendency to see Techniques as rules. Let us not forget, Techniques are
informative, whereas Principals, Guidelines and Success Criteria are
normative.

If we start treating Techniques as normative rules we might find ourselves
slipping back into the WCAG 1.0 mindset.

Regards,

Roger

The short answer is "yes" and the long answer is "it depends".

The failure is clear and DIV is not one of the allowed parameters. In
practical terms there are situations where DIV works fine, being tested with
JAWS or NVDA. Other/older screenreaders could do something different with
blocks of text in a DIV separated by BR.

There are other situations where several blocks of text are presented
visually only by CSS, i.e. <div><span>first block</span><span>second
block</span></div>. That often does not work with screenreaders, which may
treat the entire content as one paragraph. Thus, it can get difficult for
screenreaders to discover the context of a link. 

So, in doubt, DIV ist not OK.

In most situations like the above links are part of a sentence, so there are
other means for screenreader users to discover the context, and using DIV
does not invoke a failure.

Regards,
Jan
