Question regarding owl:DeprecatedClass and owl:DeprecatedProperty

Hi all,

A question has come up in the OWL working group as to whether or not 
anyone uses these constructs.  There is a proposal on the table to 
eliminate these from the language in OWL "1.1", in fact.

If anyone can cite examples of where these constructs have been used and 
provide guidance on whether or not there may be an impact if they are 
removed from the language, we would appreciate the reference.

Thanks!

Elisa
