HTML markup errors and warnings
(Rescan now...)
Errors:
Bad value “schema.DC” for attribute “rel” on element “link”: The string “schema.DC” is not a registered keyword.
An “img” element must have an “alt” attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.
Bad value “_gaq.push(['_trackEvent', 'global', 'press_releases', 'グローバルナビ'” for attribute “onclick” on element “a”: missing ] after element list
The text content of element “time” was not in the required format: The literal did not satisfy the time-datetime format.
The text content of element “script” was not in the required format: Expected space, tab, newline, or slash but found “{” instead.
Warnings:
The “navigation” role is unnecessary for element “nav”.
Section lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all sections.
Consider using the “h1” element as a top-level heading only (all “h1” elements are treated as top-level headings by many screen readers and other tools).
Article lacks heading. Consider using “h2”-“h6” elements to add identifying headings to all articles.
