I take the point - but I am not sure I understand why the case for whole pattern over substring matched differs between when they appear in a form and when they appear in a script (where substring matching is more common). Is this just an historical artifact, or is there a more fundamental reason? In any case, isn't this a case of supporting one of two alternative sources of consistency - consistency with other form interfaces, and consistency with the existing scripting enviromnent (where client-side validation is currently implemented)?
