HTML markup errors and warnings
(Rescan now...)
Errors:
Legacy doctype. Expected “<!DOCTYPE html>”.
When the attribute “xml:lang” in no namespace is specified, the element must also have the attribute “lang” present with the same value.
The “version” attribute on the “html” element is obsolete. You can safely omit it.
The “profile” attribute on the “head” element is obsolete.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.
A “meta” element with an “http-equiv” attribute whose value is “X-UA-Compatible” must have a “content” attribute with the value “IE=edge”.
Bad value “iq-af” for attribute “hreflang” on element “link”: The language subtag “iq” is not a valid ISO language part of a language tag.
Attribute “wicket:id” not allowed on element “meta” at this point.
Attribute “wicket:id” not allowed on element “link” at this point.
Attribute “wicket:id” not allowed on element “title” at this point.
Element “wicket:container” not allowed as child of element “body” in this context. (Suppressing further errors from this subtree.)
Self-closing syntax (“/>”) used on a non-void HTML element. Ignoring the slash and treating as a start tag.
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:
Attribute “wicket:id” is not serializable as XML 1.0.
Element name “wicket:container” cannot be represented as XML 1.0.
