Colorsync -- Camera profiles flawed

Using the OS X program Colorsync utility, several of the profiles supplied do not verify. Below is an example from the output of the Colorsync utility:

/Library/ColorSync/Profiles/Canon EOS-1D flash.icm
Tag 'cprt': Tag type is not correct.

When I attempt to use the Repair facility of the program, I get the following messages for each of the defective profiles:

/Library/ColorSync/Profiles/Canon EOS-1D flash.icm
Tag 'cprt': Tag type is not correct. Could not be fixed

Is there a problem with the Phase One profiles. I notice I am not getting this for the Canon 10D, which is the camera I use.

  There is several standards for how a profile should be created according to different standards over the years.
  The camera profiles are working correctly with in the Capture One application despite this message colour sync util is giving.

  Like what standards? Which standard does CO use? Isn't the point of ICC to eliminate this sort of confusion? It seems to me that either Apple or CO are out of spec.

  The answer to that is neither:
  Cprt tag is a copyright tag and by that is irrelevant to the actual function of the profile.
  Colorsync sees this as a requirement when doing a test of a profiles.
  Hope this is a good enough answer.

  It is, definitely. I wonder, however, how many users wondering about that \"glitch\" (whoever's, I do not care) read this forum, and find this thread.
  
  Since this will be happening to ALL Mac OS X users, this explanation should go in the help system.

  UlfLiljegren,
  
  Can't this tag be added in order to make the profile validate?
  The profile would no longer report an error.
  We would not experience this problem, and so this would no longer be an issue or concern to Mac users, and then think of all the time and energy that everyone could saved because you would not keep getting this question.
  
  Feasible?

  I most definitely agree with you, why create need for support when you do not have to?
  
  I will push this issue again; you have provided me with the \"gun powder\" to actually getting this fixed to avoid the question in the future.
