Validacion en html 4.01

[b44]

Hola he validado una pagina y me sale esto:
The following missing or conflicting information caused the validator to perform guesswork prior to validation. If the guess or fallback is incorrect, it may make validation results entirely incoherent. It is highly recommended to check these potential issues, and, if necessary, fix them and re-validate the document.

1.

Warning No Character Encoding Found! Using iso-8859-3.

None of the standards sources gave any information on the character encoding labeling for this document. The character encoding iso-8859-3, which you have chosen via the Encoding override option, will be used for tentative validation.

Read the FAQ entry on character encoding for more details and pointers on how to fix this problem with your document.

Congratulations

The document located at <http://xelene.sytes.net/> was tentatively checked as HTML 4.01 Transitional. This means that with the use of some fallback or override mechanism, we successfully performed a formal validation using an SGML, HTML5 and/or XML Parser(s). In other words, the document would validate as HTML 4.01 Transitional if you changed the markup to match the changes we have performed automatically, but it will not be valid until you make these changes.
Linking to this result

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://validator.w3.org/check?uri=http%3A%2F%2Fxelene.sytes.net%2F> (or you can just add the current page to your bookmarks or hotlist).
