 773          * a structured array of links usually used for the tabs in a skin
 774          *
 775          * There are 4 standard sections
 776          * namespaces: Used for namespace tabs like special, page, and talk namespaces
 777          * views: Used for primary page views like read, edit, history
 778          * actions: Used for most extra page actions like deletion, protection, etc...
 779          * variants: Used to list the language variants for the page
 780          *
 781          * Each section's value is a key/value array of links for that section.
 782          * The links themselves have these common keys:
 783          * - class: The css classes to apply to the tab
 784          * - text: The text to display on the tab
 785          * - href: The href for the tab to point to
 786          * - rel: An optional rel= for the tab's link
 787          * - redundant: If true the tab will be dropped in skins using content_actions
 788          *   this is useful for tabs like "Read" which only have meaning in skins that
 789          *   take special meaning from the grouped structure of content_navigation
 790          *
 791          * Views also have an extra key which can be used:
 792          * - primary: If this is not true skins like vector may try to hide the tab
 793          *            when the user has limited space in their browser window
 794          *
 795          * content_navigation using code also expects these ids to be present on the
 796          * links, however these are usually automatically generated by SkinTemplate
 797          * itself and are not necessary when using a hook. The only things these may
 798          * matter to are people modifying content_navigation after it's initial creation:
 799          * - id: A "preferred" id, most skins are best off outputting this preferred id for best compatibility
 800          * - tooltiponly: This is set to true for some tabs in cases where the system
 801          *                believes that the accesskey should not be added to the tab.
 802          *
 803          * @return array

1654          *
1655          * The text of the link will be generated either from the contents of the
1656          * "text" key in the $item array, if a "msg" key is present a message by
1657          * that name will be used, and if neither of those are set the $key will be
1658          * used as a message name.
1659          *
1660          * If a "href" key is not present makeLink will just output htmlescaped text.
1661          * The "href", "id", "class", "rel", and "type" keys are used as attributes
1662          * for the link if present.

1664          * If an "id" or "single-id" (if you don't want the actual id to be output
1665          * on the link) is present it will be used to generate a tooltip and

1673          *   a link in. This should be an array of arrays containing a 'tag' and
1674          *   optionally an 'attributes' key. If you only have one element you don't
1675          *   need to wrap it in another array. eg: To use <a><span>...</span></a>
1676          *   in all links use array( 'text-wrapper' => array( 'tag' => 'span' ) )
1677          *   for your options.
1678          *   - 'link-class' key can be used to specify additional classes to apply
1679          *   to all links.
1680          *   - 'link-fallback' can be used to specify a tag to use instead of "<a>"
1681          *   if there is no link. eg: If you specify 'link-fallback' => 'span' than
1682          *   any non-link will output a "<span>" instead of just text.
