Regarding Dean's answer, it may be some kind of workaround, but is
nothing near a general solution.
What if an external rule reference is done without mentioning the
rule name (because the referenced module has a root rule)?
What about a rule like the following?
  $rule =
    {$.result = $r1 + $r1};
                ^^^   ^^^

Regarding Felix Wyss's post, I'm glad to see that problems/omissions
in the SISR standard are generating more posts!
I posted two messages concerning SISR on www-voice in the last 6
months (10th June 2003, 30th July 2003), but there hasn't been
any reaction on this list.
This surprised and still surprises me, since I would imagine that
contributors to said document are subcribers of this mailing list...

Does someone know what the current status of SISR is?
Is there any revision process planned?
