Two types of classes support processing X12 Messages:

• Generic classes that are common to all types of X12 messages. There is one class for each segment in the X12 standard.
• Specific classes for a given message type (such as 837). These are sub-classes of the message type class (such as PegaX12-Data-N837). These classes contain properties that are of the appropriate PegaX12-Data-segment class.
