5/// # Field 11S: MT and Date of the Original Message
6///
7/// For Cancellation and Request for Payment messages, this field contains
8/// the message type and date of the original message that is being cancelled or referenced.
9///
10/// **Format**: 3!n6!n4!n4!n
11/// - Message Type (3 digits): The original message type (e.g., 103, 202)
12/// - Date (6 digits): YYMMDD format
13/// - Session Number (4 digits): Session of original message
14/// - Input Sequence Number (4 digits): ISN of original message
15///
16/// Note: The format may include an optional slash (/) before the input sequence number,
17/// but this is handled by the parser which strips it out before processing.
18///
19/// ## Usage
20/// - **MT192**: Request for Cancellation (Customer Transfer)
21/// - **MT292**: Request for Cancellation (Financial Institution Transfer)
22/// - References original message for processing

24/// ## Validation
25/// - Message type must be valid 3-digit MT number
26/// - Date must be valid YYMMDD format within acceptable range
27/// - Session and ISN must be 4-digit numbers
28///
29/// Example: 103231215001/0123 (MT103 dated 2023-12-15, session 0001, ISN 0123)
