/**
 * ERXWOFormBarrier allows you to wrap a section of your page that you want to trick into believing that
 * it is not actually inside of a WOForm. As an example, you could wrap an AjaxModalDialog that has a
 * form inside of it so that the form inside the dialog would process correctly because the barrier
 * would trick WO into believing the inner form is structurally distinct an outer form that might
 * already be wrapping the dialog.
