Comment (by DD32):

 Ah...
 It validates as XHTML 1.0 Transitional; However, If you validate it as
 XHTML 1.0 Strict it'll fail with this:

 {{{
 Validation Output: 1 Error
  Line 119, Column 76: document type does not allow element "input" here;
 missing one of "p", "h1", "h2", "h3", "h4", "h5", "h6", "div", "pre",
 "address", "fieldset", "ins", "del" start-tag.
 …ltered_html_comment" value="642e718613" />

 ✉

 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>").
