How do you match only valid roman numerals with a regular expression?
... and 4000. It's a relatively simple:
0: <empty> matched by M{0}
1000: M matched by M{1}
2000: MM matched by M{2}
3000: MMM matched by M{3}
4000: MMMM matched by M{4}
You could, of course, use something like M* to allow any number (including zero) of thousands, if y...

So if you are dealing with small fractions, like comp...
