The “profile” attribute on the “head” element is obsolete. To declare which “meta” terms are used in the document, instead register the names as meta extensions. To trigger specific UA behaviors, use a “link” element instead.

Using the “meta” element to specify the document-wide default language is obsolete. Consider specifying the language on the root element instead.

Bad value “cleartype” for attribute “http-equiv” on element “meta”.

A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.

Attribute “about” not allowed on element “article” at this point.

Attribute “content” not allowed on element “span” at this point.

Attribute “datatype” not allowed on element “span” at this point.

“=” in an unquoted attribute value. Probable causes: Attributes running together or a URL query string in an unquoted attribute value.

No “p” element in scope but a “p” end tag seen.

Bad value “CERN” for attribute “rel” on element “a”: The string “CERN” is not a registered keyword.
