/**
 * The beginning of an experiment to provide a capability to define
 * the sitemap menu in xml. Currently pretty limited.
 * menu elements have a name attribute, and contain text and link
 * elements, and optionally multiple menu elemnts.
 * The contents of the text element is the menu display x(ht)ml,
 * and the contents of the link element is an array of
 * path components in JSON array syntax.
