Minor personal preference... I don't like talking about "P programs", 
but rather about "P rules", since the former might get people the 
impression that P can be used to program actions.

I consider this out-of-scope for the current work. The author of the 
rules needs to know about the parameters and their types when writing 
the rules.

For example, when I'm writing rules like

   if (condition)
    invoke Service_A(p1, p2, p3)

then I assume to know about Service_A and its parameters. How I learn 
about this is out-of-scope (could be either human interaction or 
automated).
