Yes.

How about:

	(5) The '.' is used to separate the table name (component)
            and column name (property) when selecting a property that
            is contained inside of a component that is targeted in
            the TARGET property.

	    In this example the '.' is used to separate the
            TRIGGER property from its contained component (VALARM)
	    which is contained in any VEVENT in the selected TARGET
            (relcalid). All TRIGGER values in any VEVENT in relcalid
            would be returned.

		TARGET:relcalid
		QUERY: SELECT VALARM.TRIGGER FROM VEVENT
