That is intentional in the RDF Schema design: properties are a primitive
notion distinct from classes. This allows you to add your own properties
to existing classes. For example, you might define the class your:book,
with properties dc:title, dc:author, isbn:isbn, and your:rating, the last
representing what you think of the book. I could then add new properties
to the class such as my:rating or my:criticizesW3C. This is part of the
support machinery for the design principle "anyone can say anything about
anything in RDF".
