Is there some sort of shorthand going on here? Where did the ?card a
<urn:Card> statement pattern go? <urn:Card> is only a subClass of the Range
property restrictions on <urn:hasRank> and <urn:hasSuit>. Seems like you would
still need to join on <urn:Card> here unless you replace subClassOf with
equivalentClass.
