Provide validation for user input values entered during an automated installation
This is an improvement on a pending feature that was been submitted. This issue works with and IZPACK-1102.
When a user is prompted for a missing value in the auto-install.xml, the value entered should be validated by the same validators that are used during a console or gui installation. Only after all validation passes should the value be entered into installData.
I suggest that during the automated installation, the installer should read the userInputSpec.xml for any validators and validate the input before continuing.
