Good point. It could be solved by specifiying "step" as any number >0. A
borderline case would then be formed by stepsizes which are rounded off to
zero (e.g. 1e-99999), but that is already covered by the spec:
# If the author specified step is too small for the UA to handle (for
# example, 1e-9999999 would probably underflow most implementations)
# then the UA should treat the value as any.
However, given that explanation, you could also define step as any number
>=0 and define step="0" to be the same as step="any". You could even drop
the "any" this way, although many authors might find it easier to
understand than step="0".
