 815          * a structured array of links usually used for the tabs in a skin
 816          *
 817          * There are 4 standard sections
 818          * namespaces: Used for namespace tabs like special, page, and talk namespaces
 819          * views: Used for primary page views like read, edit, history
 820          * actions: Used for most extra page actions like deletion, protection, etc...
 821          * variants: Used to list the language variants for the page
 822          *
 823          * Each section's value is a key/value array of links for that section.
 824          * The links themselves have these common keys:
 825          * - class: The css classes to apply to the tab
 826          * - text: The text to display on the tab
 827          * - href: The href for the tab to point to
 828          * - rel: An optional rel= for the tab's link
 829          * - redundant: If true the tab will be dropped in skins using content_actions
 830          *   this is useful for tabs like "Read" which only have meaning in skins that
 831          *   take special meaning from the grouped structure of content_navigation
 832          *
 833          * Views also have an extra key which can be used:
 834          * - primary: If this is not true skins like vector may try to hide the tab
 835          *            when the user has limited space in their browser window
 836          *
 837          * content_navigation using code also expects these ids to be present on the
 838          * links, however these are usually automatically generated by SkinTemplate
 839          * itself and are not necessary when using a hook. The only things these may
 840          * matter to are people modifying content_navigation after it's initial creation:
 841          * - id: A "preferred" id, most skins are best off outputting this preferred id for best compatibility
 842          * - tooltiponly: This is set to true for some tabs in cases where the system
 843          *                believes that the accesskey should not be added to the tab.
 844          *
 845          * @return array

1708          * "text" key in the $item array, if a "msg" key is present a message by
1709          * that name will be used, and if neither of those are set the $key will be
1710          * used as a message name.
1711          *
1712          * If a "href" key is not present makeLink will just output htmlescaped text.
1713          * The "href", "id", "class", "rel", and "type" keys are used as attributes

1727          *   need to wrap it in another array. eg: To use <a><span>...</span></a>
1728          *   in all links use array( 'text-wrapper' => array( 'tag' => 'span' ) )
1729          *   for your options.
1730          *   - 'link-class' key can be used to specify additional classes to apply
1731          *   to all links.
1732          *   - 'link-fallback' can be used to specify a tag to use instead of "<a>"
1733          *   if there is no link. eg: If you specify 'link-fallback' => 'span' than
1734          *   any non-link will output a "<span>" instead of just text.
