Nancy - I take your point, but strictly speaking, If you dereference the URI: 
(and note that the example has a slight error, the .html should have been omitted)
and get RDF returned: 

note that it is a madsrdf:GenreForm.   (As opposed to a madsrdf:Topic. MADS doesn't know about subjects  --topics, but not subjects). 

Granted, the URI:
makes it seem to be a subject.
