Thanks, noted.

The friendlier error messages fell victim to a change in backend parser. We
used to use Liam Quinn's version of SP, but had to switch to OpenSP for
various reasons. Improving the error messages is one of the issues we'd
like to address though, so there is a chance this will improve eventually.

I don't /think/ we shortened them, but it's possible I'm misremembering.

The main issue with making them longer is that the little "^" we use to
indicate the position of the error quickly falls apart when the source line
is wider then the width of he browser window. We can probably stand to have
a few more characters shown then today, but not all that many.

For a future version we're investigating other ways to indicate the
position of the error (either as replacements for the "^", or as a
supplement to it) which may make this more robust.

Just as an aside, have you checked out the nifty report formats you can get
from Nick Kew's wonderfull Page Valet <http://valet.webthing.com/>? Take a
look at e.g.
<http://valet.webthing.com/page/v3.1?url=http%3A%2F%2Fwww.vir.si%2F&wcag=3&
fmt=HTML&xsl=wcag&parse=W3C>.

We're all envious of Nick and wish we had that output format as an option
in the Validator too. :-)



Thanks for the feedback!
