Well, sometimes the warning is that you could do better. Sometimes it is  
something that the test cannot determine. Etc.

Sure. To be interoperable you have two options. Require consuming  
technology to understand RDFS sub-properties and classes, or add both  
properties. To add both properties, I think you have two kinds of result,  
which I believe is not what we allow currently. (I am not sure what the  
logic boffins came up with about whether a result that is duplicated by a  
subClass of itself is a different kind of result, but that seems  
intuitively likely...)
