Warnings:
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
The “language” attribute on the “script” element is obsolete. You can safely omit it.
Errors:

Bad value “Cache-Control” for attribute “http-equiv” on element “meta”.
Element “input” with attribute “type” whose value is “button” must have non-empty attribute “value”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
The “cellspacing” attribute on the “table” element is obsolete. Use CSS instead.
Element “img” is missing required attribute “src”.
