The built-in validator functions are:  IsArrayKey - Checks that the value is one of the keys in the array supplied as the argument to the validator.  IsArrayValue - Checks that the value is one of the values in the array supplied as the argument to the validator.  IsEqual - Checks that the value is equal to the value supplied as the argument to the validator, allowing for standard type conversion rules.  IsGreaterThan - Checks that the value is strictly greater than a specified minimum value supplied as the argument to the validator.  IsIdentical - Checks that the value is equal to the value supplied as the argument to the validator, and has the same type.  IsInRange - Checks that the value is in a specified range between a minimum and maximum value. The minimum and maximum values are specified as a 2-element array as the argument to the validator.  IsInOptionsList-Checks against a list of options in the policy definition.  IsNonEmpty - Checks that the value is a non-empty string (length non-zero and not all whitespace), or a non-empty array.  IsNonNegative - Checks that the value is numeric and non-negative.  IsRegexMatch - Checks that the value matches a regular expression supplied as the argument the validator. The regular expression should be a Perl-compatible regular expression with delimiters. For example, the validator argument /^a/i will match any value that starts with an "a", case-insensitively. See "Regular Expressions" in this chapter for more information about regular expression syntax.  IsValidBool - Checks that the value is a standard Boolean truth value. Valid Boolean values are the integers 0 and 1 and the PHP values false and true.  IsValidDateTime - Checks that the value appears to be a valid time specification string according to the rules of the PHP function strtotime(). Valid date/time syntax includes ISO 8601 standard times (YYYY-MM-DD hh:mm:ss) with and without time zone specifications, as well as many other formats.  IsValidEmail - Checks that the value appears to be a valid RFC 822-compliant email address. When using the IsValidEmail validator, the validator argument may be specified wieth a whitelist/blacklist of domain names.
