 == Export ==

 Menus and their menu items should be included in the WXR. Switching
 can_export to true should mostly rectify this.

 However, that introduces some issues. Including them in the post type and
 taxonomy dropdowns is not intuitive. You either need to export everything,
 or just export the menu tax and item PT (and you need to know to select

 Thus to me it makes sense that can_export might need to be split into A)
 showing it in the export UI, and B) can it be included in the WXR file. We
 can then handle our own UI, perhaps with a checkbox, "Export menus and
 menu items." Or something.

 That of course brings up another concern, which is that menu items have
 associated posts, which means they need to also be exported. So really you
 should not be able to export just menus and menu items, unless of course
 all of your menu items are custom links (but how can we know that?).
 Ironically, a simplified export.php from 2.9 would have served us well
 here, as we'd always just export everything.

 == Import ==

 Offering a patch for import is particularly challenging, because we'll not
 only need to map the post-taxonomy relationships (which the importer
 should handle for menus out of the box) but also the relationships between
 a menu item and the associated post or term. That introduces new problems.
 What happens when the associated post or term is not included in the WXR
 file? Does the menu item convert to a custom link? (Is there any
 indication that it became broken on import?) Or do we decline to import
 the menu item? (What about children menu items?)

 Clearly a lot of questions here. I think it is pretty safe to say that we
 do want menus exportable (they are much more like content than basic
 settings), but the implementation will not be easy. Suggestions welcome.
