Hi,

I have consolidated the recent discussion on constratints into the wiki
page

http://code.google.com/p/umple/wiki/OCLConstraints

Luna should be able to start with the testcases and grammar at least.

To confirm, the following two constraints are equivalent

[a > 0] [a < 3000][a > 0 && a < 3000]

For clarify, I think we should either remote the "minimumAge" attribute, or
use it below in age > 10 (and make it age > minimumAge).  Finally, I would
make the less than (<) a less or equal (<=) and and the (>) a (>=) to avoid
semantic confusion (i.e. the minimum voting age is 18, so the contraint
would be [a >=  18]

class Student {

    Integer age;
    immutable Integer minimumAge = 16;

    immutable Integer maximumAge = 120;

    Integer studyYear;
    Boolean isMature;

    [minAge: age > 10]

    [maxAge: age < maximumAge]

}
