+The sidebar for MonoBook is generated from this message, lines that do not
+begin with * or ** are discarded, furthermore lines that do begin with ** and
+do not contain | are also discarded, but don't depend on this behaviour for
+future releases. Also note that since each list value is wrapped in a unique
+XHTML id it should only appear once and include characters that are legal
+XHTML id names.

+Note to translators: Do not include this message in the language files you
+submit for inclusion in MediaWiki, it should always be inherited from the
