Hi Denise,

http://www.alistapart.com/index.html is not triple-A compliant (not even
double-A compliant) but it does use stylesheets instead of tables for layout
and still works on most browsers. (It ain't the prettiest thing in older
browsers, but it works. their article http://www.alistapart.com/switcher.html
describes and links to descriptions of what they did for their site)

It is also valuable to explain to a University that there are good reasons
for supporting upgrades in default systems provided to students, especially
when they are available for free or very low cost, as with browsers. There
are now a wide range of browsers available for all kinds of platforms -
investigating the linux accessibility work might save a fair bit of money on
assistive technology, or provide some valuable research work for students,
for example.

The question of whether something worksin a particular browser could be
approached in the way that libraries do. In most universities I have been to
there are some books which have multiple copies. Different editions,
different binding, etc for the same content. I have never met a library that
is prepared to categorise the same book differently just because one copy is
red and one copy is blue. (I only ever knew one person who classified his
books by colour, and he had an exception case for multiple copies).

For what it is worth my personal opinion is that using tables for basic
layout violates checkpoint 3.1 and thus means the site cannot be double-A
compliant. Even if you decide not to use style sheets instead of tables for
layout (and the place I work for decided that in some instances) it is still
worth trying to apply all the rest of the checkpoints - each of them is
useful on its own.

cheers

  Just to clarify things a little, the training site is only meant to serve as a
  basic introduction to Web accessibility - certainly there is no assumption that
  authors will necessarily be able to create web sites that meet all the
  requirements for triple-a compliance and html 4 validation using stringent
  validation tools such as the W3C html validator. This site in an interim
  measure while we begin the task of setting University Wide standards on Web
  accessibility (which must still be endorsed by the University's Academic
  Board). I am trying to raise the consciousness of staff of the major concerns
  at this stage.

  While we prepare the standards we are also intending to develop corporate style
  sheets and templates that University staff will be required to use. The aim is
  to ensure at least a degree of compliance (we can't control everything authors
  do once they start using the templates) and also trying to establish an overall
  corporate look for all Uni Web sites. So the intention is to minimize some of
  the work for Uni Staff in the longer term.

  My dilemma is how to ensure that the site that I publish for this introduction
  to Web Accessibility is a model of good practice - even though it is likely
  staff will not be able to create a similar site without our yet to be developed
  style sheets and templates. Your advice about a page explaining how we have
  arrived at our claim for either double a or triple a compliance makes good
  sense.

  I'd still like some advice though about what actually constitutes the
  difference in compliance levels (ie does the use of a table for layout even if
  styles are used for all other markup make the site automatically only level 2
  or 3 compliant, does the use of any deprecated language to accommodate lower
  level browsers make it a level 2 or 3 site even if all other accessibility
  checkpoints are met?). Can anyone point me to a site that is triple-a
  compliant, validates as html 4 transitional AND looks fine in broken browsers
  such as NS 4? If there is a way of achieving triple-a compliance and validation
  for the site while still retaining an aesthetic look in NS 4 that is the ideal.
  This would also help me in the development of the style sheets and templates
  that will eventually be prescribed for all Uni staff.
