(Rescan now...)
Errors:
Bad value “” for attribute “target” on element “a”: Browsing context name must be at least one character long.
Attribute “tab-index” not allowed on element “a” at this point.
Element “style” not allowed as child of element “div” in this context. (Suppressing further errors from this subtree.)
No space between attributes.
Quote “"” in attribute name. Probable cause: Matching quote missing somewhere earlier.
Bad value “sitearea” for attribute “type” on element “a”: Subtype missing.
Attribute “mode” not allowed on element “a” at this point.
Attribute “end” not allowed on element “a” at this point.
Attribute “]"” not allowed on element “a” at this point.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Warnings:
The “border” attribute is obsolete. Consider specifying “img { border: 0; }” in CSS instead.
Attribute “]"” is not serializable as XML 1.0.
