Errors:

Saw “<?”. Probable cause: Attempt to use an XML processing instruction in HTML. (XML processing instructions are not supported in HTML.)

Almost standards mode doctype. Expected “<!DOCTYPE html>”.

Attribute “xmlns:aria” not allowed here.

Using the “meta” element to specify the document-wide default language is obsolete.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

Bad value “content-script-type” for attribute “http-equiv” on element “meta”.

Attribute “value” not allowed on element “input” at this point.

Warnings:

Attribute with the local name “xmlns:aria” is not serializable as XML 1.0.

The “type” attribute is unnecessary for JavaScript resources.

The “name” attribute is obsolete. Consider putting an “id” attribute on the nearest container instead.
