 Same as primary_menu() but operates on @secondary_menu.
 
+=item create_submenu()
+
+Creates XHTML for unordered list of sub-menu items which belong to a
+particular top-level menu item. Uses hover pseudo class in css to display
+dropdown list when mouse hovers over top-level item. Support for IE6
+(no hover psuedo class) via LC_hoverable class for <li> tag for top-
+level item, which employs jQuery to handle behavior on mouseover.
+
+Inputs: 6 - (a) link and (b) target for anchor href in top level item,
+            (c) title for text wrapped by anchor tag in top level item.
+            (d) reference to array of arrays of sub-menu items.
+            (e) boolean to indicate whether to call &mt() to translate
+                name of menu item,
+            (f) optional class for <li> element in primary menu, for which
+                sub menu is being generated.
+
+The underlying datastructure used in (d) contains data from mydesk.tab.
+It consists of an array which has an array for each item appearing in
+the menu (e.g. [["link", "title", "condition"]] for a single-item menu).
+create_submenu() supports also the creation of XHTML for nested dropdown
+menus represented by unordered lists. This is done by replacing the
+scalar used for the link with an arrayreference containing the menuitems
+for the nested menu. This can be done recursively so that the next menu
+may also contain nested submenus.
+
+ Example:
+ [                                                                                      # begin of datastructure
