I know that X.509 has a life outside directories and that X.509 in some
places makes unnecessary references to Directory.

Directory is not a fantasy. There many thousands or maybe millions of
Microsoft Active Directories spinning every day. A lot of other LDAP systems
are out there. All Identity Management System have a directory, mostly LDAP,
as a major component.

X.500 is also very much alive and kicking.

Just to be pedantic, I guess I should point out that since X.509 seems to be
written in terms of some fantasy entity called The Directory, it doesn't
apply
to anything that actually exists.  Applying a strict interpretation, nothing
is actually bound by X.509 in this case.
