 825          * a structured array of links usually used for the tabs in a skin
 826          *
 827          * There are 4 standard sections
 828          * namespaces: Used for namespace tabs like special, page, and talk namespaces
 829          * views: Used for primary page views like read, edit, history
 830          * actions: Used for most extra page actions like deletion, protection, etc...
 831          * variants: Used to list the language variants for the page
 832          *
 833          * Each section's value is a key/value array of links for that section.
 834          * The links themselves have these common keys:
 835          * - class: The css classes to apply to the tab
 836          * - text: The text to display on the tab
 837          * - href: The href for the tab to point to
 838          * - rel: An optional rel= for the tab's link
 839          * - redundant: If true the tab will be dropped in skins using content_actions
 840          *   this is useful for tabs like "Read" which only have meaning in skins that
 841          *   take special meaning from the grouped structure of content_navigation
 842          *
 843          * Views also have an extra key which can be used:
 844          * - primary: If this is not true skins like vector may try to hide the tab
 845          *            when the user has limited space in their browser window
 846          *
 847          * content_navigation using code also expects these ids to be present on the
 848          * links, however these are usually automatically generated by SkinTemplate
 849          * itself and are not necessary when using a hook. The only things these may
 850          * matter to are people modifying content_navigation after it's initial creation:
 851          * - id: A "preferred" id, most skins are best off outputting this preferred id for best compatibility
 852          * - tooltiponly: This is set to true for some tabs in cases where the system
 853          *                believes that the accesskey should not be added to the tab.
 854          *
 855          * @return array

1715          * @param array $item contains some of a specific set of keys.
1716          *
1717          * The text of the link will be generated either from the contents of the
1718          * "text" key in the $item array, if a "msg" key is present a message by
1719          * that name will be used, and if neither of those are set the $key will be
1720          * used as a message name.

1722          * If a "href" key is not present makeLink will just output htmlescaped text.
1723          * The "href", "id", "class", "rel", and "type" keys are used as attributes
1724          * for the link if present.
1725          *
1726          * If an "id" or "single-id" (if you don't want the actual id to be output
1727          * on the link) is present it will be used to generate a tooltip and

1738          *   - 'text-wrapper' key to specify a list of elements to wrap the text of
1739          *   a link in. This should be an array of arrays containing a 'tag' and
1740          *   optionally an 'attributes' key. If you only have one element you don't

1742          *   in all links use array( 'text-wrapper' => array( 'tag' => 'span' ) )
1743          *   for your options.
1744          *   - 'link-class' key can be used to specify additional classes to apply
1745          *   to all links.
1746          *   - 'link-fallback' can be used to specify a tag to use instead of "<a>"
1747          *   if there is no link. eg: If you specify 'link-fallback' => 'span' than
1748          *   any non-link will output a "<span>" instead of just text.
