That's not possible. Templates (I assume you're calling a template
here), do not have a return value. Since templates can contain
arbitrary complex topic map structures it is impossible to decide
which of these constructs should be returned (unless we introduce a
mechanism to let the user decide if she wants to return something).

So, you'll need one more line to model that association. ;)

We have wildcards and named wildcards. These may help in 99% of the
use cases, or in 98%, I don't know.

I understand the advantages but I don't think we should put it into
1.0.

Best regards,
