No space between attributes.

Saw “<” when expecting an attribute name. Probable cause: Missing “>” immediately before.

Attribute “<u” not allowed on element “a” at this point.

Stray end tag “u”.

The text content of element “time” was not in the required format: The literal did not satisfy the time-datetime format.

An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.

Warnings

The “type” attribute is unnecessary for JavaScript resources.

Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.

Attribute “<u” is not serializable as XML 1.0.
