On Solaris 8 there is only one line, for user_attr(4),
which pertains to users, not to files.
However, on Solaris 10 it turns up fsattr(5),
which seems to be the feature under discussion.
The Solaris 10 manual page for fsattr(5) describes
nicely how to access the attribute information, but
it fails to explain why one would want to use that
feature in the first place.

At least on Solaris 10, there is an openat() syscall
that opens the attributes as a normal fd starting at
the (possibly ordinary) fd supplied as an argument,
which acts "sort of" like a current-working-directory.

I'm still wondering what the motivation was.
