HTML markup errors and warnings
(Rescan now...)
Errors:
Element “ul” not allowed as child of element “span” in this context. (Suppressing further errors from this subtree.)
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Bad value “quickNavigation” for attribute “rel” on element “a”: The string “quickNavigation” is not a registered keyword.
The “summary” attribute on the “table” element is obsolete. Consider describing the structure of the “table” in a “caption” element or in a “figure” element containing the “table”; or, simplify the structure of the “table” so that no description is needed.
Attribute “hovercard-ref” not allowed on element “a” at this point.
Attribute “hovercard-id” not allowed on element “a” at this point.
The “itemprop” attribute was specified, but the element is not a property of any item.
