It was a URI in HTML 4 and XHTML 1.0, but was changed to IDREF in Modularaization of XHTML (and hence in XHTML 1.1) as implementation experience has showed that support for external map reference is very weak and has a lot of difficulties in implementing it. Then we got a lot of push-back as IDREF syntax is not backwards compatible. So we were inclined to go back to URI, but since XHTML 2.0 is not supposed to be backwards compatible anyway, we are reconsidering this issue again. I'd like to invite people's opinion on this issue.
