No, I think you asked the W3C Markup Validator to check whether your 
document complies with the Document Type Definition it purports to 
comply with, and it did exactly that.

It looks rather hopeless. I wonder why the page declares an XHTML 
document type when its author has clearly no idea of XHTML. Well, itís a 
mix of old-style HTML and XHTML, so validation is rather pointless. It 
will just tell you itís all wrong, but it tells that rather verbosely.

To start with, XHTML is case-sensitive. You canít just use <META> 
instead of <meta>. And in XHTML, any occurrence of ď&Ē as data character 
must be escaped (e.g. as ď&amp;Ē).

Whether itís ok to someone is irrelevant. Reportable markup errors are 
reportable independently of peopleís feelings.

You asked for a formal check and you got it.

Too bad. Mixing old-style HTML and XHTML doesnít really hurt browsers. 
But it means that you cannot effectively validate your documents. The 
mix causes so many error messages that it would take ages to distinguish 
these syntax errors from other errors that might actually affect 
browsers, search engines, or other relevant software.

No, you need to check your HTML code.
