(Rescan now...)
Errors:
Almost standards mode doctype. Expected “<!DOCTYPE html>”.
A document must not include more than one “meta” element with a “http-equiv” attribute whose value is “content-type”.
Bad start tag in “img” in “head”.
Element “head” is missing a required instance of child element “title”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Stray end tag “noscript”.
Attribute “name” not allowed on element “meta” at this point.
Element “meta” is missing one or more of the following attributes: “itemprop”, “property”.
Element “title” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)
The text content of element “script” was not in the required format: Expected space, tab, newline, or slash but found “<” instead.
Stray end tag “head”.
Start tag “body” seen but an element of the same type was already open.
Cannot recover after last error. Any further errors will be ignored.
Warnings:
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
