Congratulations
The document located at <​https://cnrtl.fr/​> was successfully checked as XHTML 1.0 Transitional. This means that the resource in question identified itself as "XHTML 1.0 Transitional" and that we successfully performed a formal validation of it. The parser implementations we used for this check are based on OpenSP (SGML/XML) and libxml2 (XML).
"valid" Icon(s) on your Web page
To show your readers that you have taken the care to create an interoperable Web page, you may display this icon on any page that validates. Here is the HTML you could use to add this icon to your Web page:
<p> <a href="http://validator.w3.org/check?uri=referer"><img src="http://www.w3.org/Icons/valid-xhtml10" alt="Valid XHTML 1.0 Transitional" height="31" width="88" /></a> </p>
A full list of icons, with links to alternate formats and colors, is available: If you like, you can download a copy of the icons to keep in your local web directory, and change the HTML fragment above to reference your local image rather than the one on this server. See also our help items related to documents transferred over secure protocols for these icons and the "uri=referer" feature.
