Alias entries in an X.500 directory are pointers used to help
overcome the limitations of any choice of hierarchy. However, an
alias entry in the directory cannot contain a certificate, or any
other data. I bemoan the fact that alias entries cannot contain
certificates.
There are alternatives to "Alias". I dont have my ISODE manual handy,
but if I recall there are at least two attributes which are called
something like PositionFilledBy and SeeAlso which if I'm not mistaken
can coexist along side Certificate attributes.
