/**
 * A validator for regular expressions.
 *
 * This validator will return true, when the passed value does *not* match
 * the regular expression.
 *
 * If you do want to test if the value *matches* an expression, you can use
 * the MatchValidator class instead.
 *
 * Below is an example usage for your Propel xml schema file.
 *
 * <code>
 *   <column name="ISBN" type="VARCHAR" size="20" required="true" />
 *   <validator column="username">
 *     <!-- disallow everything that's not a digit or minus -->
 *     <rule
 *       name="notMatch"
 *       value="/[^\d-]+/"
 *       message="Please enter a valid email adress." />
 *   </validator>
 * </code>
