Errors:

Internal encoding declaration “iso-8859-1” disagrees with the actual encoding of the document (“utf-8”).
Bad value “text/html; charset=iso-8859-1” for attribute “content” on element “meta”: “iso-8859-1” is not a preferred encoding name. The preferred label for this encoding is “windows-1252”.
Bad value “language” for attribute “http-equiv” on element “meta”.
Attribute “value” not allowed on element “meta” at this point.
Element “meta” is missing one or more of the following attributes: “content”, “property”.
Bad value “Cache-Control” for attribute “http-equiv” on element “meta”.
Bad value “Pragma” for attribute “http-equiv” on element “meta”.
Bad value “expires” for attribute “http-equiv” on element “meta”.
Self-closing syntax (“/>”) used on a non-void HTML element. Ignoring the slash and treating as a start tag.
The “align” attribute on the “div” element is obsolete. Use CSS instead.
The “center” element is obsolete. Use CSS instead.
Warnings:
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
This document appears to be written in Dutch. Consider adding “lang="nl"” (or variant) to the “html” start tag.
