/*
This script has been included freely within the ListX package in order to have a validator which works within the framework.
You may notice that this script looks remarkably like the WebUIValidation.js Framework script. This is true, however, a small
number of corrections have been made to the script to make it work in browers OTHER than Internet Explorer.

The following corrections were made:
1. Document.all replaced with document.getObjectById()
2. Event added as parameter to the ValidatorOnChange
3. Event is verified in ValidatorOnChange to fetch either target or srcElement
4. Added Conversion function which converts from direct access of custom attributes to getAttribute when not defined.
5. Added Intelligent lookup functionality to automatically populate "Page_Validators".
6. Added Intelligent lookup functionality to automatically populate "Page_ValidationSummaries".
7. Corrected the building of the prototype when firefox needs to assign via getAttribute.
