This is the entry in LCMSAPI.TXT for cmsCreateProofingTransform:

------------
  Same as cmsCreateTransform(), but including soft-proofing. The
  obtained transform emulates the device described by the
  "Proofing" profile. Useful to preview final result whithout
  rendering to physical medium.

  Parameters and returns same as anterior, but with the addition of

        Proofing: a handle to proofing profile.

        ProofingIntent: Is the intent for translating emulated
                        colors. Default is

                            INTENT_ABSOLUTE_COLORIMETRIC.

       dwFlags: 


        cmsFLAGS_GAMUTCHECK: Color out of gamut are flagged to a
                             fixed color defined by the function
                             cmsSetAlarmCodes(int r, int g, int b);
        
        cmsFLAGS_SOFTPROOFING: (Does need preview tag to work) does
                             emulate the Proofing device.


  You need to add a combination of these flags to enable any proof!
-------------

So, it goes input -> Proofed device -> Output. You can call proofer to the
output device if you prefer to do that. 
See my other post on multiprofile transforms for more details

Ah, I didn't check there, since a "tutorial" is used to show one how  
to use something, not to *explain* the API. That's what I'd expect  
from a file named LCMSAPI.TXT.

I'm still looking for an answer about why the output format space is  
being checked against the output profile space and not the proofer  
profile space.
