| Which is where the problem is- you want
|  _:a rdf:type r1:date .
|  _:a rdf:value "2004-06-04" .
|
| but after the transform you've got
|  _:a rdf:type r1:date .
|  _:a rdf:value "4th June 2004" .
|  _:a rdf:value "2004-06-04" .

Ah, I see what you mean. I understood Danny's suggestion to mean that
one begins:

_:foo ex:date _:a .
_:a rdf:type r1:date .
_:a rdf:value "2004-06-04" .

and gets:

_:foo ex:date _:a .
_:a rdf:type r1:date .
_:a rdf:value "2004-06-04" .
_:foo ex:date _:b .
_:b rdf:type r2:date .
_:b rdf:type "4th June 2004"

[which, now I look at it, could be nasty (in the xslt) if _:a is the
object in multiple statements.]

I guess we need to ask Danny what he meant.
