David,

Agreed, but both are roundish, both are fruit.  The similarities may be more
important than the differences.

Agreed.  The WAI had important influence on the HTML 4 specification.  I
think we could be taking better advantage of that.

True, and I have been free with my opinion that Bobby has become less useful
as it has tried to become more comprehensive.  I feel the same way about
Microsoft Word!

Okay, so it is possible to construct text that is perfectly grammatically
correct, but totally unintelligible.  It is also possible to construct
strictly valid HTML 4.01 documents that are totally inaccessible.  Both are
interesting academic exercises.  So what?  The same people that obsess over
grammar are also intelligible, even when they strive hard at the former and
the latter comes by accident.  Does anyone publish serious work that is
grammatically correct but unintelligible?  Can you cite a REAL example?
Don't works that are grammatically correct have a VERY strong tendency to be
intelligible?  Does anyone publish serious work that is syntactically
correct HTML 4 but violates Priority 1 checkpoints of the WCAG?  Can you
cite a REAL example?  Doesn't HTML work that is valid have a VERY strong
tendency towards accessibility?  The difficulty I have with your analogy is
that grammar can be fairly hard to test for.

I promise to shut up about this once people post a few good counter
examples!  Working URLs only please...
