RENDERZONE - render the content of a zone

$item <!--<literal> $id $missing</literal>-->

$id: requires= missing ids: $missingids

header and footer are not output if there is no content in the zone (nothing has been ADDTOZONEd ). However they are output if the output is the empty string (at least one ADDTOZONE has been processed).

Zones are cleared after being rendered; they are only ever rendered once.

head, script and body are default zones. The corresponding RENDERZONE is already included in the base foswiki.tmpl. head and script are automatically inserted before the </head> tag in the output HTML page. body is automatically inserted before the </body> tag in the output HTML page.

Macros will be expanded in all zones. TML markup will not be expanded in the head and scripts zones. Any formatting in head and scripts zones including [[TML links]] must be done directly using HTML. TML pseudo-tags like nop. verbatim, literal. and noautolink are removed from head and script zones and have no influence on the markup. All other zones will be rendered as normal topic text.

Normally, dependencies between individual ADDTOZONE statements are resolved within each zone. However, if {MergeHeadAndScriptZones} is enabled in configure, then head content which requires an id that only exists in script will be re-ordered to satisfy this dependency. {MergeHeadAndScriptZones} will be removed from a future version of Foswiki.
