If you _do_ keep track of Y in a separate repository, I think two archives
(the one that has a pointer to Y, and the other that is taken from the
repository Y _at the revision you are using_), would solve that more
naturally.  Then the version markers recorded in the archives would still
be valid.

	Side note.  If we ever teach git-archive to create a recursive
	tarball that contains a submodule, we should be doing something
	like that, not necessarily as two separate tarballs but possibly
	with a single tarball that has two comments that describe the
	revision of the toplevel and the submodule.

Under such an option, at least the comment in the archive (both for zip
and tar) that notes which revision the tarball was taken from should be
omitted.  As long as that is done, I think it is Ok to have such an
optional behaviour.
