	 *  <LI>is never a wildcard neither a regular expression

	 * <I>Performance notes</I>: at the OSF we had problems loading the configuration and
	 * creating an alarm from the default. In both cases the problems were in this method.
	 * To improve performances we made several changes and found that
	 * <UL>
	 * 	<LI>iterate over an array is faster then iterating over a {@link Collection}
	 *  <LI>comparing String seems slower then checking regurlar expression (once that it has been compiled into a pattern)
