The multiple-cnames option has nothing to do with this. He doesn't want
multiple CNAME records, he wants a CNAME with other data. This is
expressly forbidden by the DNS specification, and BIND no longer allows it.

Sorry, that's the way it is. If a name has a CNAME record, it means that
it's simply a synonym for the target name. What you're asking for would be
like creating a symbolic link on Unix and then trying to have different
data in the link versus the target file.
