Do you have to use a regular expression? I note that the Schema datatypes
spec says "Not-a-number equals itself and is greater than all float values,
including positive infinity."
Perhaps a maxInclusive of "INF"? (Disclaimer: haven't tried it)

Does something like (.-[Na])+ work? I'm unsure that . is a proper
character class that's subject to substraction.

I believe I have one somewhere that's close to being good and that could
exclude NaN. However it's several lines long (when wrapped) and last
year it tended to crash validators. I can dig it up if you don't find a
pleasant solution.
