OK, I think this may be more of a documentation issue.

If all implementations do override equals() this maybe should be added 
to and documented in the interface API to get some natural place to put 
this information.

Or could there be a reason for an implementation not to 
implement/override equals()? In that case, this really needs to be 
documented somewhere ...
