Message syntax
The type tree enforces strict message syntax that is based upon three variable values, <Tag>, <Value>, and <Delimiter>.
The field format is: <Tag>=<Value><Delimiter>. Values for these entities are described as follows:
- <Tag> - any integer with no leading zeros
- = (equal sign) - the separator between Tag and Value.
- <Value> - value that represents the actual content of the field
- <Delimiter> - a non-printing ASCII character that is called the SOH character
