End tag “div” seen, but there were open elements.
Unclosed element “nav”.
Element “span” not allowed as child of element “hgroup” in this context. (Suppressing further errors from this subtree.)
Element “hgroup” is missing a required instance of one or more of the following child elements: “h1”, “h2”, “h3”, “h4”, “h5”, “h6”.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.

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

Empty heading.
The document is not mappable to XML 1.0 due to two consecutive hyphens in a comment.
