CTS211 — CTS2: "entityType" description text incorrect - needs to be updated

The current description of entityType in section 2.1.1.1 of the Entity Description Services (page 6) reads:
entityType - the set of type(s) which the entityReference is an instance of. Because this is a terminology service, entityType must include one of owl:class, owl:individual, rdf:predicate, or skos:concept, although it may carry many other types as well.

This is incorrect - it should read:
"... must include one of owl:Class, owl:Individual, rdf:Property or skos:Concept"

Note that this may potentially effect some implementations that have either transcribed the information literally or have used "rdf:predicate" instead of "ref:Property"
