HeaderLength (4 bytes): 0x00000008 specifies the number of bytes in the DataSpaceDefinition before the TransformReferences field.
TransformReferenceCount (4 bytes): 0x00000001 specifies the number of items in the TransformReferences array.
TransformReferences (variable): "DRMEncryptedTransform" specifies the transform associated with this DataSpaceDefinition structure. This string is contained in a UNICODE-LP-P4 structure (section 2.1.2); therefore, the first 4 bytes of the structure contain 0x0000002A, which specifies the length, in bytes, of the string. The string is not null-terminated; however, the structure is padded with 2 bytes to ensure that its length is a multiple of 4 bytes. "DRMEncryptedTransform" matches the name of the transform storage contained in the \0x06DataSpaces\TransformInfo storage (section 2.2.3).
