| Actually, no. The TM author is the only one to judge that there is a
| relationship at all between the topic and its occurrence, and the
| nature of this relationship. Like any other TM assertion in fact.

That's not entirely correct, as Piotr points out. As the SAM says:

  An occurrence is a relationship between an information resource and
  a subject. The precise nature of this relationship is described by
  the occurrence type, a subject which is attached to the
  occurrence. Occurrences are generally used to attach information
  resources to the subjects they are relevant to.

In other words, the other subject must be an information resource if
you are going to use an occurrence, and the occurrence is the
relationship between the subject and the resource, not the resource
itself.

Also, occurrences are there in order for you to attach relevant
resources to a subject (relevant, not just any resources), though the
standard does not formally require this to be the case.
