doc/ref: add spec for bounds

Bound is an easy spec (piggy backed on comparisons
and allows expressing things that are currently impossible
to express. Once added, we could seriously consider removing
ranges.

open ranges:
a: >=1 & <5.0 // open range

positive: >0 // allows 1e-100, but not 0

exclude values:
b: null | a1 | … | an
b: !=null

nonZero: !=0
