Is there any documentation for layout resource XML files such as schemas/.xsd's? It states in the second paragraph in the Overview section of the Menu2 documentation: "While a Menu2 can be generated programmatically, they should generally be created as a resource." I'm trying to do just that but after using search engines, searching through the SDK directories and documentation, and browsing this forum I haven't come across concrete documentation of what specific elements and fields are valid in these files.
