Errors:
Self-closing syntax (“/>”) used on a non-void HTML element. Ignoring the slash and treating as a start tag.
The element “header” must not appear as a descendant of the “header” element.
Element “style” not allowed as child of element “header” in this context. (Suppressing further errors from this subtree.)
Bad value “//www.w3.org/2000/svg” for the attribute “xmlns” (only “http://www.w3.org/2000/svg” permitted here).
Stray end tag “svg”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Attribute “type” not allowed on element “video” at this point.

Warnings:
Attribute “xmlns” is not serializable as XML 1.0.
The first occurrence of ID “Rectangle_2_copy” was here.
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
