These functions are services themselves and should be invoked by the 
rules, rather then trying to "programm" them in the rules.

If a function like "adding of authentication controls" is needed, a 
little service doing this can be written, and a rule can be specified 
to invoke this service.

Thats sounds worthwhile to consider (but already goes beyond the 
charter discussion perse, I would assume).

Such mechanism is needed (one might default to existing ones), but out 
of scope of the WG.
