Errors:
A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
Saw “<!--” within a comment. Probable cause: Nested comment (not allowed).
The “center” element is obsolete. Use CSS instead.
End tag “div” seen, but there were open elements.
Unclosed element “center”.

Attribute “page” not allowed on element “div” at this point.
Attribute “rev” not allowed on element “div” at this point.
The “rev” attribute on the “div” element is obsolete. Use the “rel” attribute instead, with a term having the opposite meaning.
Bad value “feedback” for attribute “rel” on element “a”: The string “feedback” is not a registered keyword.
Bad value “forgot” for attribute “rel” on element “a”: The string “forgot” is not a registered keyword.
The “for” attribute of the “label” element must refer to a non-hidden form control.
Warnings:
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.

This document appears to be written in Russian but the “html” start tag has “lang="en"”. Consider using “lang="ru"” (or variant) instead.
