 816          * namespaces: Used for namespace tabs like special, page, and talk namespaces
 817          * views: Used for primary page views like read, edit, history
 818          * actions: Used for most extra page actions like deletion, protection, etc...
 819          * variants: Used to list the language variants for the page
 820          *
 821          * Each section's value is a key/value array of links for that section.
 822          * The links themselves have these common keys:
 823          * - class: The css classes to apply to the tab
 824          * - text: The text to display on the tab
 825          * - href: The href for the tab to point to
 826          * - rel: An optional rel= for the tab's link
 827          * - redundant: If true the tab will be dropped in skins using content_actions
 828          *   this is useful for tabs like "Read" which only have meaning in skins that
 829          *   take special meaning from the grouped structure of content_navigation
 830          *
 831          * Views also have an extra key which can be used:
 832          * - primary: If this is not true skins like vector may try to hide the tab
 833          *            when the user has limited space in their browser window
 834          *
 835          * content_navigation using code also expects these ids to be present on the
 836          * links, however these are usually automatically generated by SkinTemplate
 837          * itself and are not necessary when using a hook. The only things these may
 838          * matter to are people modifying content_navigation after it's initial creation:
 839          * - id: A "preferred" id, most skins are best off outputting this preferred
 840          *   id for best compatibility.
 841          * - tooltiponly: This is set to true for some tabs in cases where the system
 842          *   believes that the accesskey should not be added to the tab.
