In this case, the error is (mostly) caused by the use of unquoted 
attribute values, which violate XHTML rules.

By changing the doctype from XHTML 1.0 Transitional to HTML 4.01 
Transitional, the number of error messages is reduced from 230 to 55.

But the document contains a mix of XHTML (like "/" in so-called 
self-closing tags, like <meta name="..." content="..." />) and classic 
HTML (like unquoted attribute values). This does not matter to browsers, 
but it matters in validation. So you need to decide between HTML 4.01 
and XHTML 1.0 and use it consistently. Unless you expect your document 
to be processed, I would recommend HTML 4.01. (You can still quote all 
attribute values if you like. But you cannot e.g. use "/" in some 
"self-closing tags" and omit it from others.)
