No, but I can prove you right. See the fourth bullet point at
  <URL: http://www.topicmaps.org/xtm/1.0/#conf-doc >

You can do it easily, as Tony says, but no topic map implementation
will support it. Another question is why you would want to. If you
want to say something about the relationship between an instance and
its class topic maps offer you ways to do that *within* the TM
paradigm.

It's http://www.topicmaps.org/xtm/1.0/.
