 /**

  * This is a constraint that limits attribute values to some subset of valid characters or to match a particular regular expression.

  * 

  * For example: 

  * - To limit to both upper and lower-case letters, value can be set to "[A-Za-z]*"

  * - To limit to any character except carriage returns and line feeds, value can be set to "[^\n\r]*"

  * 

  * Alternative processors can be specified, though the current implementation (1.1) does not handle any processor but regex. 

  * TODO delyea: remove jsValue from docs here

  * Note that if jsValue has any value it will always <b>override</b> the following...<b>

  * If the labelKey matches one of the following values:<br>

  *                 email<br>

                 url<br>

                 date<br>

                 number<br>

                 digits<br>

                 creditcard<br>

                 letterswithbasicpunc<br>

                 alphanumeric<br>

                 lettersonly<br>

                 nowhitespace<br>

                 integer<br>

                 phoneUS<br>

                 time<br>

  * or <b>any</b> other custom method added through the addMethod call on the validator in jQuery 

  * AND if a javascript value is not specified on this constraint, it will use the built in jQuery defined

  * validation method which matches that name.  Note using a validator method here which is not a regex validation does not

  * make sense within context of this constraint as a server side regex value should be defined.
