Accessibility Error Messages

Hi,

The code for accessibility testing was done independently of tidy and integrated
later on. Therefore its purpose can be difficult to trace. I think
that the reference
document is http://www.w3.org/TR/WAI-WEBCONTENT/.
That is what I added in:
http://tidy.cvs.sourceforge.net/tidy/tidy/src/access.c?view=markup

The first three digits relates to the reference document.
The last digit is related to the test cases. It is rather weird to
emit it in the
error messages. Again this was not the choice of any tidy developer.

Incidentally, the test cases has been added to the tidy distribution a while
back and enhanced since then. As well, some obsolete tests have been
removed.

Regards,
