In the document "Representing Classes As Property Values on the Semantic Web"
at http://www.w3.org/TR/swbp-classes-as-values/, the example right before
the section header "Considerations when choosing Approach 4" says:

   :LionsLifeInThePrideBook
       a       :Book;
       [ a       owl:Restriction ;
                 owl:onProperty dc:subject ;
                 owl:someValuesFrom :Lion
       ];
       rdfs:seeAlso <http://isbn.nu/0736809643> ;
       :bookTitle "Lions: Life in the Pride" .

Is there an "a" (rdf:type) missing?  Should it have said the following?:

   :LionsLifeInThePrideBook
       a       :Book;
       a [ a       owl:Restriction ;
       ...
