/**
* InputTextMask script used for mask/regexp operations.
* Mask Individual Character Usage:
* 9 - designates only numeric values
* L - designates only uppercase letter values
* l - designates only lowercase letter values
* A - designates only alphanumeric values
* X - denotes that a custom client script regular expression is specified</li>
* All other characters are assumed to be "special" characters used to mask the input component.
* Example 1:
* (999)999-9999 only numeric values can be entered where the the character
* position value is 9. Parenthesis and dash are non-editable/mask characters.
* Example 2:
* 99L-ll-X[^A-C]X only numeric values for the first two characters,
* uppercase values for the third character, lowercase letters for the
* fifth/sixth characters, and the last character X[^A-C]X together counts
* as the eighth character regular expression that would allow all characters
* but "A", "B", and "C". Dashes outside the regular expression are non-editable/mask characters.
* @constructor
* @param (String) mask The InputTextMask
* @param (boolean) clearWhenInvalid True to clear the mask when the field blurs and the text is invalid. Optional, default is true.
