The entire profile, based on the size field in the header, is used to calculate the ID with the exception of the Rendering intent, Header attributes, and Profile ID fields in the profile header for which zeros are used instead of their actual values. A Profile ID value of zero indicates the ID has not been calculated. However, it is strongly recommended that profile creators do calculate and fill in the correct value in the Profile ID field.
