Dear all,

Following this September message, I am proposing to close this issue 
formally.

This said, location is so weakly specified in the model, that it begs 
the question "what
does it do in the model at all". No specific data type, no specific 
property, no specific
constraint, no specific inference.  As part of the clean up, we could 
simply drop this
concept, and it wouldn't affect inter-operability!

If you have views on this, please raise them as new issues.

Regards,
Luc
