 802          *
 803          * There are 4 standard sections
 804          * namespaces: Used for namespace tabs like special, page, and talk namespaces
 805          * views: Used for primary page views like read, edit, history
 806          * actions: Used for most extra page actions like deletion, protection, etc...
 807          * variants: Used to list the language variants for the page
 808          *
 809          * Each section's value is a key/value array of links for that section.
 810          * The links themselves have these common keys:
 811          * - class: The css classes to apply to the tab
 812          * - text: The text to display on the tab
 813          * - href: The href for the tab to point to
 814          * - rel: An optional rel= for the tab's link
 815          * - redundant: If true the tab will be dropped in skins using content_actions
 816          *   this is useful for tabs like "Read" which only have meaning in skins that
 817          *   take special meaning from the grouped structure of content_navigation
 818          *
 819          * Views also have an extra key which can be used:
 820          * - primary: If this is not true skins like vector may try to hide the tab
 821          *            when the user has limited space in their browser window
 822          *
 823          * content_navigation using code also expects these ids to be present on the
 824          * links, however these are usually automatically generated by SkinTemplate
 825          * itself and are not necessary when using a hook. The only things these may
 826          * matter to are people modifying content_navigation after it's initial creation:
 827          * - id: A "preferred" id, most skins are best off outputting this preferred
 828          *   id for best compatibility.
 829          * - tooltiponly: This is set to true for some tabs in cases where the system
 830          *   believes that the accesskey should not be added to the tab.
 831          *
