So it could in principle be recalculated at any time by the parameters.
Wouldn't this also mean that one could take the affected pixels at a
later stage without really storing them by just addressing them by means
of the original module? (I'm definitley not at home in the program logic
here.)
I think this goes a bit in the direction of Markus idea. I admit that I
thought that the blendif() works on selections based on the raw image,
but thinking about it this might not make sense if I want to select an
area after some initial processing. Thus it seems difficult to work like
Markus suggested.

Probably not. I wonder thogh, how gimp and friends does it if one stores
a mask or a channel.

Definitely not in xml. Agreed. ;)
