Schema error

originalMessageType 00557 not accepted by feedback schema 001.02

Symptom

A feedback message on a corporate action (message 15) with originalMessageType = 00557 gives a schema error on originalMessageType.

Cause

Feedback schema 001.02 (pre-release 2027) enumerates 0001a to 00556 and lacks 00557; message 15 was added in the same release.

Fix

Omit originalMessageType (optional) and refer with originalMessageId; report the omission to SIVI via GitHub so the final release 2027 corrects it.
