I hereby modify my proposal to the use of a modifier "op", as you suggest,
but
it must give specific authority for the use of the record with each specific
protocol in a comma-separated list, e.g.
"op=pra,smm"
So now the PRA test may only be applied if the "pra" identifier is among the
values in the "op" list.
The name of the modifier should obviously be "ot" .
So a typical entry is now:
"ot=pra,smm"
So after couple thoughts you came back with what is basicly same concept
as sc= modifier for which I've been advocating for a while, see
