A real message using tag 458

Where tag 458 appears

Requiredness is a property of the message, not of the field: the same tag can be optional in one message and conditionally required in another.

Wire format

Free-form text. Any byte except the SOH separator is legal, so values are not trimmed or case-folded on the wire. @boarteam/fix keeps the value as a string; format rules are checked by validate(), which reports validate/invalid-value rather than throwing.
