Oops, I got it wrong.

According to a third party, the RDF schema defines something called "typed
nodes", which operate as if they were descriptions with the rdf:type element
set.

So,

<Topic rdf:ID="foo">
  <dc:title>Foo</dc:title>
</Topic>

is semantically equivalent to:

<rdf:Description rdf:ID="foo">
  <rdf:type resource="Topic"/>
  <dc:title>Foo</dc:title>
</rdf:Description>

My apologies for the confusion.

Will.
