I disagree. A (single) topic always represents a single subject
*by definition*. (Of course, that might be a complex subject,
like "The members of WG3", but it's still a single subject.)
A single subject, on the other hand, may be represented by
multiple topics. Within a single topic map we try to avoid
this, in order to achieve subject collocation (aka SLUO),
but we cannot guarantee that we always succeed.
