I can't see any reason for treating NOTIFY from REFER differently from any other NOTIFY. E.g., NOTIFY from REFER is within the same dialog as the REFER, just as NOTIFY from SUBSCRIBE is within the dialog established by the SUBSCRIBE. And it's clear that all in-dialog requests should have the proper Contact value for their end of the dialog.
