Raw data with no format or content restrictions. Data fields are always immediately preceded by a length field. The length
field should specify the number of bytes of the value of the data field (up to but not including the terminating SOH). Caution:
the value of one of these fields may contain the delimiter (SOH) character. Note that the value specified for this field should
be followed by the delimiter (SOH) character as all fields are terminated with an "SOH".
Sequence of digits with optional decimal point and sign character (ASCII characters "-", "0" - "9" and "."); the absence of
the decimal point within the string will be interpreted as the float representation of an integer value. All float fields
must accommodate up to fifteen significant digits. The number of decimal places used should be a factor of business/market
needs and mutual agreement between counterparties.
Sequence of digits without commas or decimals and optional sign character (ASCII characters "-" and "0" - "9" ). The sign
character utilizes one byte (i.e. positive int is "99999" while negative int is "-99999"). Examples: 723 in field 21 would
be mapped int as |21=723|, -723 in field 12 would be mapped int as |12=-723|.
