	Yes, subdirectories inherit their parents <DirectoryDirs> and
<AppDirs>. Its kind of hidden in the language:

  "Each directory listed in a <DirectoryDir> element will be searched
   for directory entries to be used when resolving the <Directory>
   element for this menu and its submenus."

	I'm not sure I follow what you're saying, but having

  <DefaultDirectoryDirs/>

	is exactly identical to having

  <DirectoryDir>~/.local/share/desktop-directories</DirectoryDir>
  <DirectoryDir>/usr/local/share</DirectoryDir>
  <DirectoryDir>/usr/share</DirectoryDir>

	so all submenus of the <Menu> that contained <DefaultDirectoryDirs/>
should also search the default dirs.

Cheers,
Mark.
