It looks as if I was subtly wrong. There is no fixed source RRD file.

But I do have a black box test that behaves differently with different versions of
RRDtool. The test code generates its own RRD source file ("rrd create", performs some
operation on it ("rrd update"), does an XML dump ("rrdtool dump") and compares that
against a known good ("diff").

I'll try to look into it.
