+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
+	["/home/", "Home", "condition1"], 		# 1st item of the 1st layer menu
+	[										# 2nd item of the 1st layer menu
+		[									# anon. array for nested menu
+			["/path1", "Path1", undef], 	# 1st item of the 2nd layer menu
+			["/path2", "Path2", undef], 	# 2nd item of the 2nd layer menu
+			[								# 3rd item of the 2nd layer menu
+				[[...], [...], ..., [...]],	# containing another menu layer
+				"Sub-Sub-Menu",				# title for this container
+				undef
+			]
+		],									# end of array/nested menu
+		"Sub-Menu",							# title for the container item
+		undef
+	]										# end of 2nd item of the 1st layer menu
+]
