      I used http://validator.w3.org/ to Validate this:

      This was the error report generated:


      Result: Failed validation, 8 errors
      File: upload://Form Submission
      Encoding: utf-8
      Doctype: (no Doctype found)
      Root Namespace: http://www.w3.org/1999/xhtml

      No DOCTYPE found! Attempting validation with HTML 4.01 Transitional.

      The DOCTYPE Declaration was not recognized or is missing. This
      probably means that the Formal Public Identifier contains a spelling error,
      or that the Declaration is not using correct syntax. Validation has been
      performed using a default "fallback" Document Type Definition that closely
      resembles "HTML 4.01 Transitional", but the document will not be Valid
      until you have corrected this problem with the DOCTYPE Declaration.

      Learn how to add a doctype to your document from our FAQ.
      Namespace Found in non-XML Document

      Namespace "" found, but document type is not XML!

      This page is not Valid (no Doctype found)!

      Below are the results of attempting to parse this document with an SGML parser.

      1. Error Line 1 column 0: no document type declaration; implying
      "<!DOCTYPE HTML SYSTEM>".

      <html>

      The checked page did not contain a document type ("DOCTYPE")
      declaration. The Validator has tried to validate with a fallback DTD, but
      this is quite likely to be incorrect and will generate a large number of
      incorrect error messages. It is highly recommended that you insert the
      proper DOCTYPE declaration in your document -- instructions for doing this
      are given above -- and it is necessary to have this declaration before the
      page can be declared to be valid.

      ?
      2. Error Line 2 column 2: "DOCTYPE" declaration not allowed in instance.

      <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0
      Strict//EN" "http://www.w3.org/T

      ?
      3. Error Line 2 column 124: there is no attribute "XMLNS".

      ...1/DTD/xhtml1-strict.dtd"><html xmlns="http://www.w3.org/1999/xhtml">

      You have used the attribute named above in your document, but the
      document type you are using does not support that attribute for this
      element. This error is often caused by incorrect use of the "Strict"
      document type with a document that uses frames (e.g. you must use the
      "Transitional" document type to get the "target" attribute), or by using
      vendor proprietary extensions such as "marginheight" (this is usually fixed
      by using CSS to achieve the desired effect instead).

      This error may also result if the element itself is not supported in
      the document type you are using, as an undefined element will have no
      supported attributes; in this case, see the element-undefined error message
      for further information.

      How to fix: check the spelling and case of the element and
      attribute, (Remember XHTML is all lower-case) and/or check that they are
      both allowed in the chosen document type, and/or use CSS instead of this
      attribute.

      ?
      4. Error Line 2 column 154: document type does not allow element "HTML"
      here.

      ... xmlns="http://www.w3.org/1999/xhtml">

      The element named above was found in a context where it is not
      allowed. This could mean that you have incorrectly nested elements -- such
      as a "style" element in the "body" section instead of inside "head" -- or
      two elements that overlap (which is not allowed).

      One common cause for this error is the use of XHTML syntax in HTML
      documents. Due to HTML's rules of implicitly closed elements, this error
      can create cascading effects. For instance, using XHTML's "self-closing"
      tags for "meta" and "link" in the "head" section of a HTML document may
      cause the parser to infer the end of the "head" section and the beginning
      of the "body" section (where "link" and "meta" are not allowed; hence the
      reported error).

      ?
      5. Error Line 5 column 65: character data is not allowed here.

      ...ESCRIPTION" content="content secription goes here" />

      You have used character data somewhere it is not permitted to
      appear. Mistakes that can cause this error include putting text directly in
      the body of the document without wrapping it in a container element (such
      as a <p>aragraph</p>) or forgetting to quote an attribute value (where
      characters such as "%" and "/" are common, but cannot appear without
      surrounding quotes).

      ?
      6. Error Line 13 column 6: end tag for element "HEAD" which is not open.

      </head>

      The Validator found an end tag for the above element, but that
      element is not currently open. This is often caused by a leftover end tag
      from an element that was removed during editing, or by an implicitly closed
      element (if you have an error related to an element being used where it is
      not allowed, this is almost certainly the case). In the latter case this
      error will disappear as soon as you fix the original problem.

      If this error occured in a script section of your document, you
      should probably read this FAQ entry.

      ?
      7. Error Line 14 column 5: document type does not allow element "BODY"
      here.

      <body>

      ?
      8. Error Line 31 column 7: "HTML" not finished but document ended.

      </html>

          OK, I think I get what you are after now. "All XHTML elements must be
          nested within the <html> root element". The doctype isn't an element. It
          should always be the very first thing. Except in XHTML it should really be
          the second thing, preceded by an XML declaration, but everyone leaves that
          out anyway.

            Hmmm...
            I think I get it. The XML declaration ( version, etc) should precede the
            doctype.
            I fell into using XHTML by accident and have not really taken much time to
            learn the basics.

            These helped:

              Yes, should. But you mustn't. No one uses it because it puts IE in Quirks
              Mode. You are fine without as long as you keep to Ascii characters (if you
