	(or the wizard finishes); otherwise, the current page stays up.

	The default implementation returns \c true.

	When possible, it is usually better style to disable the \uicontrol
	Next or \uicontrol Finish button (by specifying \l{mandatory fields} or
	reimplementing isComplete()) than to reimplement validatePage().
