The following notes and warnings highlight missing or conflicting information which caused the validator to perform some guesswork prior to validation, or other things affecting the output below. If the guess or fallback is incorrect, it could make validation results entirely incoherent. It is highly recommended to check these potential issues, and, if necessary, fix them and re-validate the document.
Using experimental feature: HTML5 Conformance Checker.
The validator checked your document with an experimental feature: HTML5 Conformance Checker. This feature has been made available for your convenience, but be aware that it may be unreliable, or not perfectly up to date with the latest development of some cutting-edge technologies. If you find any issues with this feature, please report them. Thank you.
The document located at <http://wwwpre.uji.es/upo/rest/publicacion/accesibilidad?mapaId=273514382&contenidoId=768350104&idioma=CA&personaId=7910> was successfully checked as HTML5. This means that the resource in question identified itself as "HTML5" and that we successfully performed a formal validation of it. The parser implementations we used for this check are based on validator.nu (HTML5).
If you would like to create a link to this page (i.e., this validation result) to make it easier to revalidate this page in the future or to allow others to validate your page, the URI is <http://static.uji.es/w3c-validator/check?uri=http%3A%2F%2Fwwwpre.uji.es%2Fupo%2Frest%2Fpublicacion%2Faccesibilidad%3FmapaId%3D273514382%26contenidoId%3D768350104%26idioma%3DCA%26personaId%3D7910> (or you can just add the current page to your bookmarks or hotlist).
