Validar blogs de Blogger en w3 validator

!Qué desastre!

El simple hecho de plantearse validar mi blog bajo los estandares de la w3 gracias a su herramienta validator es una cosa bastante deprimente... pero más deprimente es cuando te atreves y te lanzas e introduces tu URL en el validator ... tachán ! aparecen el simpático mensaje:

Result: Failed validation, 880 errors

Y todo esto con Doctype: -//W3C//DTD XHTML 1.0 Transitional//ES ... que imagínate qué pasaría si fuera Strict ... en fin si alguien sabe de alguna solución para validar el código de un blog de blogger que me lo diga y ya de paso que me explique estos errores (ya que estos atributos no se pueden cambiar de ninguna de las maneras...) Blogger genera mucho código que no es validable ni aceptado por la w3 , esa es la conclusón a la que ha llegado este humilde usuario.

Algunos errores:

Error Line 2 column 51: there is no attribute "XMLNS:B".

...ttp://www.w3.org/1999/xhtml' xmlns:b='http://www.google.com/2005/gml/b' xmlns

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. If you received this error when using the

element to incorporate flash media in a Web page, see the FAQ item on valid flash.

1. Error Line 2 column 97: there is no attribute "XMLNS:DATA".

2. Error Line 2 column 146: there is no attribute "XMLNS:EXPR".

   ...google.com/2005/gml/data' xmlns:expr='http://www.google.com/2005/gml/expr'>

3. Error Line 4 column 84: end tag for element "META" which is not open.

   ...FCPy+5LjXV8=' name='verify-v1'>>

   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.
