That's true, we're not talking about the 'cvs tag' command, but just
about symbolic names for revisions.

Exactly. What's the need to add a "reference" (svn copy) to a particular
revision of the repository, when that it's already solved by the
revision system? We just need a symbolic name, to be able to remember
the revision we want to checkout from the repository.

It is :(
