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

1820          * If an "id" or "single-id" (if you don't want the actual id to be output

1833          *   a link in. This should be an array of arrays containing a 'tag' and
1834          *   optionally an 'attributes' key. If you only have one element you don't
1835          *   need to wrap it in another array. eg: To use <a><span>...</span></a>
1836          *   in all links use array( 'text-wrapper' => array( 'tag' => 'span' ) )
1837          *   for your options.
1838          *   - 'link-class' key can be used to specify additional classes to apply
1839          *   to all links.
1840          *   - 'link-fallback' can be used to specify a tag to use instead of "<a>"
1841          *   if there is no link. eg: If you specify 'link-fallback' => 'span' than
1842          *   any non-link will output a "<span>" instead of just text.
