I've always been uncomfortable with the idea, which has been expressed
from time to time, that CLDR is merely a data format for ICU, instead of
being generally usable by applications and libraries that have nothing
to do with ICU.

Mark and Markus will recall that I expressed similar discomfort back in
2002, when BOCU-1 was specified in terms of ICU-based "sample" code
instead of an actual specification, and when the conformance test was
"make sure your implementation generates the same output as the sample
