Fatal Error: No DOCTYPE specified!

I could not parse this document, because it does not include a DOCTYPE Declaration. A DOCTYPE Declaration is mandatory for most current markup languages and without such a declaration it is impossible to validate this document.

You should place a DOCTYPE declaration as the very first thing in your HTML document. For example, for a typical XHTML 1.0 document:

      <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
        "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
      <html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en">
        <head>
          <title>Title</title>
        </head>

        <body>
          <!-- ... body of document ... -->
        </body>
      </html>
    

For XML documents, you may also wish to include an "XML Declaration" even before the DOCTYPE Declaration, but this is not well supported in older browsers. More information about this can be found in the XHTML 1.0 Recommendation.

The W3C QA Activity maintains a List of Valid Doctypes that you can choose from, and the WDG maintains a document on "Choosing a DOCTYPE".
