* TRegularExpressionValidator class
*
* TRegularExpressionValidator validates whether the value of an associated
* input component matches the pattern specified by a regular expression.
*
* You can specify the regular expression by setting the {@link setRegularExpression RegularExpression}
* property. Some commonly used regular expressions include:
* <pre>
* French Phone Number: (0( \d|\d ))?\d\d \d\d(\d \d| \d\d )\d\d
* French Postal Code: \d{5}
* German Phone Number: ((\(0\d\d\) |(\(0\d{3}\) )?\d )?\d\d \d\d \d\d|\(0\d{4}\) \d \d\d-\d\d?)
* German Postal Code: (D-)?\d{5}
* Email Address: \w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*
* Japanese Phone Number: (0\d{1,4}-|\(0\d{1,4}\) ?)?\d{1,4}-\d{4}
* Japanese Postal Code: \d{3}(-(\d{4}|\d{2}))?
* P.R.C. Phone Number: (\(\d{3}\)|\d{3}-)?\d{8}
* P.R.C. Postal Code: \d{6}
* P.R.C. Social Security Number: \d{18}|\d{15}
* U.S. Phone Number: ((\(\d{3}\) ?)|(\d{3}-))?\d{3}-\d{4}
* U.S. ZIP Code: \d{5}(-\d{4})?
* U.S. Social Security Number: \d{3}-\d{2}-\d{4}
* </pre>
*
* Note, the validation succeeds if the associated input control contains empty input.
* Use a {@link TRequiredFieldValidator} to ensure the input is not empty.
