Having all three is best (formal spec, prose spec, and sample
instances), if they're all available. But I think I'd still
pick the formal spec if I were forced to choose just one.
There's an issue of quality, too. A prose spec written by, say,
James Clark, is often sufficient, whereas one written by, say,
Dave Winer may not be any more informative than the collection
of sample instances.
With a formal notation, you can usually count on at least _some_
degree of precision.
