So in the case of an RGB printer profile to be used primarily with RGB

the RGB profile that will typically be used by source images, or an RGB
profile with a wider gamut?
OK, there is some confusion due to my using "CMYK profile" when
I really mean "printer gamut profile". Basically the perceptual
intent table is the one that is expected to do gamut mapping,
so use the opposite gamut (display <=> printer) as the source
gamut for a "generic" profile. If you know what source color space
you are going to be converting from though, then use that gamut, you
will get the best results.
Ah - that's probably what I'd missed - I'll experiment with these
settings... Just out of interest, what are the defaults?
I think they are 0 (but I'm not sure without eyeballing the code).
It doesn't actually make much difference unless the source and
destination viewing conditions are different.
