Viewing XML Message Schema
If a message schema exists for a message, click the message name in the Message Schema grid to view the schema details in the Schema Viewer page (IB_SCHEMABUILD_SEC).
This example illustrates the Schema Viewer page. The example shows schema details for version 1 of the QE_FLIGHTPLAN message definition which is a rowset message.

Note:
For easier viewing, highlight the data with your cursor.
Message schemas for rowset-based messages are read-only. You can edit message schemas for nonrowset-based messages.
