Nothing non-mon there I see.

Three triples

_:a rdf:type r1:date .
_:a xxx:transform eg:r2-to-r1.xsl .
_:a rdf:value "4th June 2004" .

We might expect xxx:transform to have semantics along the lines of

"the object of this statement is an XSLT transform that when applied to 
the subject serialized in such-and-such a way gives additional triples 
that are also true."

This could constitute a semantic extension to RDF as defined in RDF 
Semantics.

Given this the three triples are monotonic in that if we delete any of 
them the result still holds.

The hardest bit I see is the "such-and-such": I think TriX would make it 
easier. RDF/XML has too much variability.

FWIW I agree with Damian that it might be better to hang this off a class.
