I have sucessfully validated the axiom

 <AnnotationPropertyRange>
     <AnnotationProperty IRI="http://www.w3.org/2002/03owlt/AnnotationProperty/consistent004#ap"/>
     <AbbreviatedIRI>xsd:string</AbbreviatedIRI>
 </AnnotationPropertyRange>

against the new schema, which failed with the old schema. 
My concern has been addressed, thanks. 

Regards 

Michael
