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Using the “meta” element to specify the document-wide default language is obsolete.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

Saw “<!--” within a comment. Probable cause: Nested comment (not allowed).
The “align” attribute on the “img” element is obsolete. Use CSS instead.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.

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