Many Document Types based on XML need a mandatory xmlns attribute on the root element. For example, the root element for XHTML might look like:
Line 2, column 1 : Missing xmlns attribute for element html. The value should be: http://www.w3.org/1999/xhtml
< html lang="en"> end tag for element X which is not open
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 occurred in a script section of your document, you should probably read this FAQ entry.

element X undefined
You have used the element named above in your document, but the document type you are using does not define an element of that name. 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 "Frameset" document type to get the "
" element), by using vendor proprietary extensions such as "" or "" (this is usually fixed by using CSS to achieve the desired effect instead).
by using upper-case tags in XHTML (in XHTML attributes and elements must be all lower-case).

end tag for X omitted, but OMITTAG NO was specified
You may have neglected to close an element, or perhaps you meant to "self-close" an element, that is, ending it with "/>" instead of ">".
