Ahh ok - I thought you meant that those libraries had built in progressive features that we have not come across (rather than the ease with which you can transform elements into widgets when it is enabled).
It is an interesting side topic - but I wonder how much effort we would put into it given that we are not developing internet websites, but rather intranet applications. I would have thought that our customers would have complained long ago if we were developing things that their disabled employees could not use.

As we use jQuery and jQueryUI extensively, I am still quite interested
in
your assertion that they are fine examples of how to develop your website.
It could be that we are not taking advantage of some compliant things we could so it would be useful to know - but just how to you do that when Javascript is turned off? jQuery and jQuery UI won't load and therefore none of the features there-in work.<<
The approach is to build the site without JavaScript first then introduce it progressively. Clearly JQuery does not load if JavaScript is turned off. So your basic site has buttons and links to make it work as it would in the good old days (when javaScript was the much hated language it isn't today).
Then if JavaScript is enabled (you don't even need to check) you remove those and replace them with fancier widgets etc. by adding the new objects to the DOM or manipulating CSS classes (piece of cake with jQuery)
Here is a perfect example on the human rights web site. With JavaScript enabled the user can click the plus sign to expand the accordion and the relevant content is displayed (this could even be grabbed from a page further down using an Ajax call). If JavaScript disabled the page renders the normal list of hyperlinks that where there in the first place (perfect).

I confess I am not perfect but I learn more about what the site needs to do by trying to do it this way (rather than being left with the knowledge that this ain't going to work for some people) and it does give a great sense of satisfaction. In fact the site just "feels" more complete IMHO
Nice to know all visitors to your site can use it!

The disability discrimination act came into force in 1995 (I believe). You can download details from the following site (if you can but find the relevant link?).

As a note this is a perfect example of a site that functions if JavaScript is disabled yet provides very nice "progressive" enhancements when it is enabled (as is the case for the majority of users), a very fine example to us all, try it with and without JS.
