 846          * a structured array of links usually used for the tabs in a skin
 847          *
 848          * There are 4 standard sections
 849          * namespaces: Used for namespace tabs like special, page, and talk namespaces
 850          * views: Used for primary page views like read, edit, history
 851          * actions: Used for most extra page actions like deletion, protection, etc...
 852          * variants: Used to list the language variants for the page
 853          *
 854          * Each section's value is a key/value array of links for that section.
 855          * The links themselves have these common keys:
 856          * - class: The css classes to apply to the tab
 857          * - text: The text to display on the tab
 858          * - href: The href for the tab to point to
 859          * - rel: An optional rel= for the tab's link
 860          * - redundant: If true the tab will be dropped in skins using content_actions
 861          *   this is useful for tabs like "Read" which only have meaning in skins that
 862          *   take special meaning from the grouped structure of content_navigation
 863          *
 864          * Views also have an extra key which can be used:
 865          * - primary: If this is not true skins like vector may try to hide the tab
 866          *            when the user has limited space in their browser window
 867          *
 868          * content_navigation using code also expects these ids to be present on the
 869          * links, however these are usually automatically generated by SkinTemplate
 870          * itself and are not necessary when using a hook. The only things these may
 871          * matter to are people modifying content_navigation after it's initial creation:
 872          * - id: A "preferred" id, most skins are best off outputting this preferred id for best compatibility
 873          * - tooltiponly: This is set to true for some tabs in cases where the system
 874          *                believes that the accesskey should not be added to the tab.
