This group is kind of a miscellaneous group that includes constraints for dates, boolean values, email format, and most interestingly, regular expression patterns. Let's start with the simplest group, the boolean value constraints. They are pretty self-explanatory and are AssertTrue and AssertFalse. They ensure that either a value is true or false. The next group of constraints validate date values. They are Future, FutureOrPresent, Past, and PastOrPresent.
