Hi Dom,

I've updated the Contacts spec inline with this feedback. The relevant CVS
diff is here:
http://dev.w3.org/cvsweb/2009/dap/contacts/Overview.html.diff?r1=1.86&r2=1.87&f=h

Please take a look and let me know if there are still any items that you
would like me to address further.

Thanks,

Rich
