 753          * a structured array of links usually used for the tabs in a skin
 754          *
 755          * There are 4 standard sections
 756          * namespaces: Used for namespace tabs like special, page, and talk namespaces
 757          * views: Used for primary page views like read, edit, history
 758          * actions: Used for most extra page actions like deletion, protection, etc...
 759          * variants: Used to list the language variants for the page
 760          *
 761          * Each section's value is a key/value array of links for that section.
 762          * The links themseves have these common keys:
 763          * - class: The css classes to apply to the tab
 764          * - text: The text to display on the tab
 765          * - href: The href for the tab to point to
 766          * - rel: An optional rel= for the tab's link
 767          * - redundant: If true the tab will be dropped in skins using content_actions
 768          *   this is useful for tabs like "Read" which only have meaning in skins that
 769          *   take special meaning from the grouped structure of content_navigation
 770          *
 771          * Views also have an extra key which can be used:
 772          * - primary: If this is not true skins like vector may try to hide the tab
 773          *            when the user has limited space in their browser window
 774          *
 775          * content_navigation using code also expects these ids to be present on the
 776          * links, however these are usually automatically generated by SkinTemplate
 777          * itself and are not necessary when using a hook. The only things these may
 778          * matter to are people modifying content_navigation after it's initial creation:
 779          * - id: A "preferred" id, most skins are best off outputting this preferred id for best compatibility
 780          * - tooltiponly: This is set to true for some tabs in cases where the system
 781          *                believes that the accesskey should not be added to the tab.
 782          *
 783          * @return array

1613          * $item is an array containing some of a specific set of keys.
1614          * The text of the link will be generated either from the contents of the "text"
1615          * key in the $item array, if a "msg" key is present a message by that name will
1616          * be used, and if neither of those are set the $key will be used as a message name.
1617          * If a "href" key is not present makeLink will just output htmlescaped text.
1618          * The href, id, class, rel, and type keys are used as attributes for the link if present.
1619          * If an "id" or "single-id" (if you don't want the actual id to be output on the link)
1620          * is present it will be used to generate a tooltip and accesskey for the link.
1621          * If you don't want an accesskey, set $item['tooltiponly'] = true;
1622          * $options can be used to affect the output of a link:
1623          *   You can use a text-wrapper key to specify a list of elements to wrap the
1624          *     text of a link in. This should be an array of arrays containing a 'tag' and
1625          *     optionally an 'attributes' key. If you only have one element you don't need
1626          *     to wrap it in another array. eg: To use <a><span>...</span></a> in all links
1627          *     use array( 'text-wrapper' => array( 'tag' => 'span' ) ) for your options.
1628          *   A link-class key can be used to specify additional classes to apply to all links.
1629          *   A link-fallback can be used to specify a tag to use instead of <a> if there is
1630          *   no link. eg: If you specify 'link-fallback' => 'span' than any non-link will
1631          *   output a <span> instead of just text.
