The requirements imposed on the href attribute by the specified DTD (which is 
surprisingly obsolete) that the validator will check against are:

  href        %URI;          #IMPLIED  -- URI for linked resource --

Which expands to:

<!ENTITY % URI "CDATA"
    -- a Uniform Resource Identifier,
       see [URI]
    -->

Where CDATA is defined as:

This is definitely one of the latter, so what the validator says in this 
instance is not very relevant.
