 787          * a structured array of links usually used for the tabs in a skin
 788          *
 789          * There are 4 standard sections
 790          * namespaces: Used for namespace tabs like special, page, and talk namespaces
 791          * views: Used for primary page views like read, edit, history
 792          * actions: Used for most extra page actions like deletion, protection, etc...
 793          * variants: Used to list the language variants for the page
 794          *
 795          * Each section's value is a key/value array of links for that section.
 796          * The links themselves have these common keys:
 797          * - class: The css classes to apply to the tab
 798          * - text: The text to display on the tab
 799          * - href: The href for the tab to point to
 800          * - rel: An optional rel= for the tab's link
 801          * - redundant: If true the tab will be dropped in skins using content_actions
 802          *   this is useful for tabs like "Read" which only have meaning in skins that
 803          *   take special meaning from the grouped structure of content_navigation
 804          *
 805          * Views also have an extra key which can be used:
 806          * - primary: If this is not true skins like vector may try to hide the tab
 807          *            when the user has limited space in their browser window
 808          *
 809          * content_navigation using code also expects these ids to be present on the
 810          * links, however these are usually automatically generated by SkinTemplate
 811          * itself and are not necessary when using a hook. The only things these may
 812          * matter to are people modifying content_navigation after it's initial creation:
 813          * - id: A "preferred" id, most skins are best off outputting this preferred id for best compatibility
 814          * - tooltiponly: This is set to true for some tabs in cases where the system
 815          *                believes that the accesskey should not be added to the tab.
 816          *
 817          * @return array

1664          *
1665          * The text of the link will be generated either from the contents of the
1666          * "text" key in the $item array, if a "msg" key is present a message by
1667          * that name will be used, and if neither of those are set the $key will be
1668          * used as a message name.
1669          *
1670          * If a "href" key is not present makeLink will just output htmlescaped text.
1671          * The "href", "id", "class", "rel", and "type" keys are used as attributes
1672          * for the link if present.

1674          * If an "id" or "single-id" (if you don't want the actual id to be output
1675          * on the link) is present it will be used to generate a tooltip and
1676          * accesskey for the link.

1683          *   a link in. This should be an array of arrays containing a 'tag' and
1684          *   optionally an 'attributes' key. If you only have one element you don't
1685          *   need to wrap it in another array. eg: To use <a><span>...</span></a>
1686          *   in all links use array( 'text-wrapper' => array( 'tag' => 'span' ) )
1687          *   for your options.
1688          *   - 'link-class' key can be used to specify additional classes to apply
1689          *   to all links.
1690          *   - 'link-fallback' can be used to specify a tag to use instead of "<a>"
1691          *   if there is no link. eg: If you specify 'link-fallback' => 'span' than
1692          *   any non-link will output a "<span>" instead of just text.
