Table C.7-22 specifies the Attributes of the Palette Color Lookup Table Module, which describe the Lookup table data for images with Palette Color photometric interpretation.
When the Palette Color Lookup Table Module is present in an Image IOD, the conditional requirements for the use of Palette Color Lookup Table Data (0028,1201-1203) and Segmented Palette Color Lookup Table Data (0028,1221-1223), described in Table C.7-22, shall take precedence over the conditional requirements described in the Image Pixel Module (see Section C.7.6.3). When the Palette Color Lookup Table Module is present in a Presentation State IOD, the Palette Color Lookup Table Data (0028,1201-1203) Attributes are mandatory and the Segmented Palette Color Lookup Table Data (0028,1221-1223) shall not be present. When the Palette Color Lookup Table Module is present in a Color Palette IOD, either the Palette Color Lookup Table Data (0028,1201-1203) or Segmented Palette Color Lookup Table Data (0028,1221-1223) Attributes may be used.
When the Palette Color Lookup Table Module is present in a Color Palette IOD, the 3rd value of Palette Color Lookup Table Descriptor (0028,1101-1103) (i.e, the number of bits for each entry in the Lookup Table Data) shall be 8.

This Attribute uniquely identifies a palette color lookup table set (red, green, blue).
This can be used to avoid reloading a palette if a system already has that palette loaded without examining all the data entries in the palette.
If this Attribute is present in a Color Palette IOD, it shall have the same value as the SOP Instance UID.
