Markup Validation Service
Check the markup (HTML, XHTML, …) of Web documents
The following notes and warnings highlight missing or conflicting information which caused the validator to perform some guesswork prior to validation, or other things affecting the output below. If the guess or fallback is incorrect, it could make validation results entirely incoherent. It is highly recommended to check these potential issues, and, if necessary, fix them and re-validate the document.
No Character Encoding Found!
Falling back to
UTF-8.
None of the standards sources gave any information on the character encoding
labeling for this document. Without encoding information
it is impossible to reliably validate the document. As a fallback
solution, the "UTF-8"
encoding was used to read the content and attempt to perform the validation,
but this is likely to fail for all non-trivial documents.
Read the FAQ entry on character encoding for more details and pointers on how to fix this problem with your document.
No Character encoding declared at document level
No character encoding information was found within the document, either in an HTML meta element or an XML declaration. It is often recommended to declare the character encoding in the document itself, especially if there is a chance that the document will be read from or saved to disk, CD, etc.
See this tutorial on character encoding for techniques and explanations.

Column 1:
Missing xmlns attribute for element html. The value should be: http://www.w3.org/1999/xhtml
<html>
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:
<html xmlns="http://www.w3.org/1999/xhtml">

document type does not allow element "h2" here; missing one of "object", "applet", "map", "iframe", "button", "ins", "del" start-tag
<h2>Search Results in XML:</h2>The mentioned element is not allowed to appear in the context in which you've placed it; the other mentioned elements are the only ones that are both allowed there and can contain the element mentioned. This might mean that you need a containing element, or possibly that you've forgotten to close a previous element.
One possible cause for this message is that you have attempted to put a block-level element (such as "<p>" or "<table>") inside an inline element (such as "<a>", "<span>", or "<font>").
