19 
 * TRegularExpressionValidator class
20 
 *
21 
 * TRegularExpressionValidator validates whether the value of an associated
22 
 * input component matches the pattern specified by a regular expression.
23 
 *
24 
 * You can specify the regular expression by setting the {@link setRegularExpression RegularExpression}
25 
 * property. Some commonly used regular expressions include:
26 
 * <pre>
27 
 * French Phone Number: (0( \d|\d ))?\d\d \d\d(\d \d| \d\d )\d\d
28 
 * French Postal Code: \d{5}
29 
 * German Phone Number: ((\(0\d\d\) |(\(0\d{3}\) )?\d )?\d\d \d\d \d\d|\(0\d{4}\) \d \d\d-\d\d?)
30 
 * German Postal Code: (D-)?\d{5}
31 
 * Email Address: \w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*
32 
 * Japanese Phone Number: (0\d{1,4}-|\(0\d{1,4}\) ?)?\d{1,4}-\d{4}
33 
 * Japanese Postal Code: \d{3}(-(\d{4}|\d{2}))?
34 
 * P.R.C. Phone Number: (\(\d{3}\)|\d{3}-)?\d{8}
35 
 * P.R.C. Postal Code: \d{6}
36 
 * P.R.C. Social Security Number: \d{18}|\d{15}
37 
 * U.S. Phone Number: ((\(\d{3}\) ?)|(\d{3}-))?\d{3}-\d{4}
38 
 * U.S. ZIP Code: \d{5}(-\d{4})?
39 
 * U.S. Social Security Number: \d{3}-\d{2}-\d{4}
40 
 * </pre>
41 
 *
42 
 * Note, the validation succeeds if the associated input control contains empty input.
43 
 * Use a {@link TRequiredFieldValidator} to ensure the input is not empty.
