I think the intention is that this color space is the "blending" color
space. When each color is specified with a color space it is immediately
converted from that space to the deviceN blending space. The deviceN
blending space is then used to figure out what (for instance) a
combination of 50% of two spot colors amounts to (an average in blending
space). If you then render onto another color space other than deviceN,
the blending space result is converted from that to the destination
space before blending there is done.
