I think that there is a difference of recognition to "ProofingIntent" in
between us and them.

In "LCMSAPI.TXT", they are describing in the explanation of
"cmsCreateProofingTransform" function 
as follows:

> ProofingIntent: Is the intent for translating emulated colors.

I guess that four words "into Output color space" are missing. 


# I forgot to explain the following in the last message.
# They are the one having described it based on an actual function
definition.
#
#   [Input]->(Intent)->[PCS]->(Intent*1)->[Proofing]->
#         ->(Rel. colorimetric)->[PCS]->(ProofingIntent)->[Output]
#
# *1 If Intent is Absolute colorimetric, it is replaced with Relative
colorimetric.
#
# In the above chart, if ProofingProfile is NULL, the chart is changed as
follows:
#
#   [Input]->(Intent)->[PCS]->(Intent)->[Output]
