I speak to the contrary.

Here is an example that is an OWL 1.0 DL and is not in OWL 1.1 DL as 
currently defined.

eg:ap rdf:type owl:AnnotationProperty .
rdfs:label rdf:type owl:AnnotationProperty .
eg:c rdf:type owl:Class .
eg:c eg:ap _:x .
_:x rdf:type owl:Thing .
_:x rdfs:label "No longer allowed." .

Hence OWL 1.1 does not provide the same facility as in OWL 1.0, and 
there is an issue to address.
