+ * DESCRIPTION
+ * Additional Screen Color Characterization Function Sets are
+ * managed on a global basis. This means that with exception
+ * of the provided DD color spaces:
+ * RGB and RGBi
+ * DD color spaces may have different XcmsColorFormat IDs between
+ * clients. So, you must be careful when using XcmsColorFormat
+ * across clients! Use the routines XcmsFormatOfPrefix()
+ * and XcmsPrefixOfFormat() appropriately.
+ *
+ * RETURNS
+ * XcmsSuccess if succeeded, otherwise XcmsFailure
+ *
+ * CAVEATS
+ * Additional Screen Color Characterization Function Sets
+ * should be added prior to any use of the routine
+ * XcmsCreateCCC(). If not, XcmsCCC structures created
+ * prior to the call of this routines will not have had
+ * a chance to initialize using the added Screen Color
+ * Characterization Function Set.
