Placeholder for UX Component validation error messages

Description

This property is optional. Specify a placeholder for where global UX component validation errors should be shown. If you don't specify a value, a default location will be used. If your component uses Panels, then it is recommended that you specify a placeholder here; otherwise any error messages will be shown in a pop-up window. If you do not want the error messages to shown in a pop-up window specify <No Alert> as the value for the placeholder.
