It doesn't follow that the destination of a 303 has a
specific topic so <subjectIndicatorRef> is not
equivalent.

Using the examples from the httpRange-14 draft finding
you could have these URIs

   http://example.com/ontology/metre
   http://example.com/ontology/kilogram
   http://example.com/ontology/watt

all 303 to

   http://example.com/ontology/SI/Information

which then provides RDF and/or HTML descriptions of
hundreds of SI units, no one of which can be said to
be the primary topic of the resource.
