Beyond common markup languages such as XHTML 1.0 Strict, XHTML 1.1, and HTML5 (and many older
versions), Total Validator also supports HTML + RDFa 1.1, XHTML + RDFa 1.1, HTML5 used as a polyglot language,
and even XHTML5. Accessibility can be checked at all levels of WCAG, as well as according to Section 508. The spell
checker supports American and British English, French, Italian, Spanish, and German.
Total Validator provides screenshots for analyzing web page appearance in different browsers, including various
versions of Firefox from version 1.5, Internet Explorer from version 5.5, Konqueror 3.5, Lynx 2.8, Opera, and Safari.
An interesting option is that the validation result can be saved as HTML and opened with a single click on the
button Last Results the next time the tool is executed.
