Access: [13.2.1.2]: Metadata missing (link element)
(Priority 2)

Cause:

If metadata is specified via the link element its value should be a URI. It should not be used to access style sheets. Use metadata to describe or provide specific information about individual web documents. Metadata often includes a list of keywords enabling search engines to conduct a more accurate and refined search. It can also contain content ratings, author information, site maps, stream channel definitions, a document's primary language, and digital library collections.
