qname matching

Hi,

http://www.w3.org:80/2000/10/swap/test/n3/test_results.html 

in http://www.dajobe.org/2004/01/turtle/tests/rdf-schema.ttl

the ending line is ": :seeAlso <http://www.w3.org/2000/01/rdf-schema-more> ." 
the subject is ":" 

in http://www.dajobe.org/2004/01/turtle/tests/rdfs-namespace.ttl

there is

  rdf:type a rdf:Property;
  :comment "Indicates membership of a class";
  :domain :Resource;
  :isDefinedBy rdf:;
  :label "type"@en;
  :range :Class .

one of the object is "rdf:"

according to n3 specification of qname

    qname 
    (([A-Z_a-zÀ-ÖØ-öø-˿Ͱ-ͽͿ-῿‌-‍⁰-↏Ⰰ-⿯、-퟿豈-﷏ﷰ-�𐀀-󯿿][\-0-9A-Z_a-z·À-ÖØ-öø-ͽͿ-῿‌-‍‿-⁀⁰-↏Ⰰ-⿯、-퟿豈-﷏ﷰ-�𐀀-󯿿]*)?:)?[A-Z_a-zÀ-ÖØ-öø-˿Ͱ-ͽͿ-῿‌-‍⁰-↏Ⰰ-⿯、-퟿豈-﷏ﷰ-�𐀀-󯿿][\-0-9A-Z_a-z·À-ÖØ-öø-ͽͿ-῿‌-‍‿-⁀⁰-↏Ⰰ-⿯、-퟿豈-﷏ﷰ-�𐀀-󯿿]*

the qname ':' and 'rdf:" can not be matched
