Each datatype can define a set of "parameters." So a datatype can define
range facets by itself, then it can just reject anything that falls out
of that range. Everything is up to datatypes.

See attached zip file for an example. This "hex" datatype validates
hexadecimal digits, and it comes with the "max" and "min" facets which
allow you to restrict a range.
