Sure - it wasn't meant to be an exhaustive list :-)

Uh huh - and since the URI field is already in the IAFA templates,
it would seem sensible to have a separate template to deal with at
least the URN to URL mapping. I can't recall having seen anything
along these lines, but perhaps I've not been looking in the right
places ?

Perhaps we can get away with something as simple as this...

URN-TO-URL-MAPPING:
URN: // as per current internet draft
Multiple occurrences of the following block of fields
URL: // physical address of object
end of multiple occurrences
END URN-TO-URL-MAPPING

Nah, that's a shootout!
