// * the BODY class is must be set to filename base for all pages except level 1.0 index pages. Those are set to "index".
// * the BODY REL attribute is always set to the name of the zone, which is the same as the ID of the zone's LI global-nav label container.
// * The tertiary navigation scheme is different for zones with actual tertiary navigation and those with only Secondary navigation presented in the left-margin.
