That is the definitive reference – the details are further down in that
section. Specifically in "10.1.1 RDFa Vocabulary Entailment" [1].

(Granted, that in turn says: "The relevant rules are, using the rule
identifications in section 4.3 of [OWL2-PROFILES]): prp-spo1, prp-eqp1,
prp-eqp2, cax-sco, cax-eqc1, and cax-eqc2." – i.e. in [2].)

Cheers,
Niklas
