I think you might want to place the library class header file, and the
library instance, under MdeModulePkg. It's okay for the shell
application (or shell libraries) to depend on library classes / library
instances from MdeModulePkg, but -- I think -- it's not okay for a
driver in MdeModulePkg, such as PartitionDxe, to depend on a class +
instance from under ShellPkg.

Thanks!
