The eComponentType enumeration is used to select a component bitness when multiple bitnesses might exist for the same component.

 typedef  enum 
 {
   eCT_UNKNOWN = 0x00000000,
   eCT_32BIT = 0x00000001,
   eCT_64BIT = 0x00000002,
   eCT_NATIVE = 0x00001000
 } eComponentType;

eCT_UNKNOWN:   The component bitness is unknown to the client. The server MUST select the native bitness of the component if it exists; otherwise, the server MUST select the non-native bitness of the component.

eCT_32BIT:   The server MUST select the 32-bit bitness of the component.

eCT_64BIT:   The server MUST select the 64-bit bitness of the component.

eCT_NATIVE:   The server MUST select the native bitness (see section 3.1.4.4) of the component.
