2.2.1.3 Marshaling Referenced Data Types
This section describes an array of N data type instances, each referencing by offset another data type instance.
In this case, the custom-marshaled data contains N Fixed_Portion blocks (one for each main data type instance), followed by M additional Fixed_Portion blocks (one for each referenced data type instances), followed by the Variable_Data block containing data referenced by offset from all Fixed_Portion blocks. The order in which the referenced data type instances Fixed_Portion block arrays are marshaled is the order in which the corresponding offset fields are defined in the main data type instance.

Fixed_Portion_1 (variable): The Fixed_Portion block of the first data type instance in the array.
Fixed_Portion_N (variable): The Fixed_Portion block of the last data type instance in the array.
Referenced_Fixed_Portion_1 (variable): The Fixed_Portion block of the first referenced data type instance in the array.
Referenced_Fixed_Portion_M (variable): The Fixed_Portion block of the last referenced data type instance in the array.
Variable_Data (variable): A sequence of zero or more optional fields (or variable-length fields). The data in this field is referenced by offset from the Fixed_Portion blocks and the Referenced_Fixed_Portion blocks.
