Validator Services
Validator Services
There are many html validator services available - many of which are
summarized at http://www.htmlhelp.com/links/validators.htm. These are
general HTML validators. They can be used to make sure that the html is
compliant with the W3C standards used by most vendors that are developing
text reader programs.
One of the first steps in designing for accessibility
is to assure that your html can be interpreted. Some of the validators
listed will also discover missing alt="" strings and other things that need
to be fixed for accessibility.
Of course you can use the W3C validator at
http://validator.w3.org/.
Validators come in many flavors ranging from the
commercial http://www.htmlvalidator.com/htmldownload.html to the free
http://watson.addy.com/ (Dr. Watson online validator - which shows much
promise).
Some are specialized like Bobby for accessibility.

Web Accessibility page (http://www.aasa.dshs.wa.gov/access/tools.htm) as a
good general tool with some accessibility functions.
Another such tool for
accessibility is found at http://aprompt.snow.utoronto.ca/ and called the
A-Prompt Project. There most recent release is May 7, 2000 and can be
downloaded from http://aprompt.snow.utoronto.ca/develop/demo.htm.
