           Summary: Duplicate warning when "automatic" doctype fallback in
                    effect

When running with the default options (i.e no doctype or fbd set) on documents
without a doctype declaration, check outputs both warning 09 ("DOCTYPE Fallback
in effect!" - stating a fallback to HTML 4.01 Transitional) and warning 16 ("No
DOCTYPE Found! Falling Back to XHTML 1.0 Transitional.")

It should probably be only warning 16.
