[Lcms-user] What are cmsSigMCHxData?

[Andrea G. <da...@ti...>]

Hi,

Looking at lcms2.h I found a set of ICC color space constants in the 
form of cmsSigMCHxData.
I made a search for them in the ICC 4.2 standard but I didn't found them.
Are they included in the next standard?
Are they similar to cmsSigxcolorData?

Thanks a lot
Andrea
