Let me see.

1. The RDF working group defines RDF and RDFS, including the useful  
utility properties rdfs:label, rdfs:comment, rdfs:seeAlso and  
rdfs:isDefinedBy.

2. RDF people start to use these properties in conformance with the  
specs.

3. While defining OWL-DL, the OWL WG introduces rather arbitrary  
restriction on all these properties.

4. OWL people ask RDF people to stop subclassing these properties in  
order to meet the restrictions imposed by OWL-DL.

This doesn't make any sense to me. The OWL WG blundered when they  
redeclared these properties as annotation properties.

+1. You broke it, you fix it.
