These errata have the status of “Working Draft.”
Editorial change (added 6 March 2014). Add the following grammar productions in section 4 “CSS Qualified Names”:
qname : qname_prefix? ident ; wqname : wqname_prefix? ident ; wqwname : wqname_prefix? [ ident | '*' ] ;
These definitions are not used in the specification itself, but they are defined here so that other specifications can use them.
