An option in a menu of a document format. Options can specify hierarchical menus using colons, so, for example menu options "hippocampus:CA1" and "hippocampus:CA3" should produce a menu containing the item "hippocampus" which leads to a submenu containing "CA1" and "CA3".
The name of the menu option object is the text to be used in the menu. There are no other fields.
