Could we see some examples of this usage in the wild? I have been  
asked that re: the ID-based reification and am in the process of  
collecting examples.

Could you please be more specific about what these situations are? If  
we are going to base decisions on such I would like to have something  
that we can think about.

So are there bugs. Shall we include those in the spec as well?

Interesting point to cut the quote. Note the similarity of point 1 in

I have never understood this point of view. The OWL 1.1 submission  
was one of several starting points. It is the working group that  
defines the features of OWL 2, without any presumption to default  
acceptance of any of the inputs.
