 857          *
 858          * There are 4 standard sections
 859          * namespaces: Used for namespace tabs like special, page, and talk namespaces
 860          * views: Used for primary page views like read, edit, history
 861          * actions: Used for most extra page actions like deletion, protection, etc...
 862          * variants: Used to list the language variants for the page
 863          *
 864          * Each section's value is a key/value array of links for that section.
 865          * The links themselves have these common keys:
 866          * - class: The css classes to apply to the tab
 867          * - text: The text to display on the tab
 868          * - href: The href for the tab to point to
 869          * - rel: An optional rel= for the tab's link
 870          * - redundant: If true the tab will be dropped in skins using content_actions
 871          *   this is useful for tabs like "Read" which only have meaning in skins that
 872          *   take special meaning from the grouped structure of content_navigation
 873          *
 874          * Views also have an extra key which can be used:
 875          * - primary: If this is not true skins like vector may try to hide the tab
 876          *            when the user has limited space in their browser window
 877          *
 878          * content_navigation using code also expects these ids to be present on the
 879          * links, however these are usually automatically generated by SkinTemplate
 880          * itself and are not necessary when using a hook. The only things these may
 881          * matter to are people modifying content_navigation after it's initial creation:
 882          * - id: A "preferred" id, most skins are best off outputting this preferred
 883          *   id for best compatibility.
 884          * - tooltiponly: This is set to true for some tabs in cases where the system
 885          *   believes that the accesskey should not be added to the tab.
