Definitely. Uses of the information include:
1) In the absence of any better information from XSL or CSS, a browser could
use that information to apply suitable local display rules for integers:
12,000 vs 12.000 for example.
2) An editor can complain if you try to edit that field outside of its range,
and the editor can provide the option of using a slider to select approximate
values from 0-20,000.

One would hope so. If it does *more* than that then something other than the
data model is at fault :-)
