Errors:
Non-space characters found without seeing a doctype first. Expected “<!DOCTYPE html>”.
Element “head” is missing a required instance of child element “title”.
Stray doctype.
Stray start tag “html”.
Stray start tag “head”.
Attribute “http-equiv” not allowed on element “meta” at this point.
Element “meta” is missing one or more of the following attributes: “itemprop”, “property”.
Element “link” is missing one or more of the following attributes: “href”, “property”, “resource”.
A “link” element must not appear as a descendant of a “body” element unless the “link” element has an “itemprop” attribute or has a “rel” attribute whose value contains “dns-prefetch”, “pingback”, “preconnect”, “prefetch”, “preload”, “prerender”, or “stylesheet”.
Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.
Element “title” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)
Attribute “name” not allowed on element “meta” at this point.
Stray end tag “head”.
Start tag “body” seen but an element of the same type was already open.
Saw “<” when expecting an attribute name. Probable cause: Missing “>” immediately before.
A slash was not immediately followed by “>”.
Attribute “<” not allowed on element “article” at this point.
Attribute “div” not allowed on element “article” at this point.
Warnings:
Attribute “<” is not serializable as XML 1.0.
Article lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all articles.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
