Sorry I don't understand what you are asking. When you set up the
configuration for your build, you can decide whatever files you want in your
system image, so you would just have your library's XML file included. When
market runs, it asks the system what shared libraries are available (which
is just an array of library package names), and sends this information to
the server for it to appropriately filter the apps that are shown.
