Provisional MRG
A Provisional MRG is a set of provisional MRG entries, to which such entries can be added, removed or modified, as specified by term selection instructions, and that are ultimately further processed to result in a proper MRG.
The list of term selection instructions that are used to create a provisional MRG (and ultimately a proper MRG) are in the versions
section of the SAF of the scope of which the MRG is a part.
