Yes, of course. But who's going to need that? The meta files are there
to describe regular unix files. They're just exported using a file
system name space. I don't think we need metadata to describe metadata.
Assuming someone adds a directory inside a file where user can add some
attributes/streams/resource forks. As Linus said, they are just
attributes, even if they seem to behave like normal files, they're not,
they belong to the real file. Adding attributes to attributes to
attributes? That would be like adding ACLS to ACLS. Hello the
madness. ;-)

There really should be a point where you can't recurse further. Assume
there is a backup application that always tries to open every dentry it
finds as directory and then recurse. Oops. :-)
