In (1) it says an annotation property cannot have a class as a value; in 
(2) it says it can.  Could someone please clarify this?


(1) http://www.w3.org/TR/owl-ref/

"OWL DL allows annotations on classes, properties, individuals and 
ontology headers, but only under the following conditions:

     * ...
     * ...
     * The object of an annotation property must be either a data 
literal, a URI reference, or an individual."


(2) http://www.w3.org/TR/swbp-classes-as-values/

"Note that rdfs:seeAlso is an annotation property and hence giving it a 
value that is a class does not take us out of OWL DL."


Thanks,
David
