You can use Designer to view the IS document types for each FIX message type. IS document types are located in the wm.fix.rec.FIX* package as part of the WmFIXMessages, where FIX* is the FIX message version. For example, the folder FIX40 contains the IS document types that correspond to the FIX message version 4.0.

Each IS document adheres to the naming convention, FIX <FIX version><message type>, where FIX version is the version of FIX message and message type is the FIX message type. For example, “FIX40Advertisement” is the IS document for FIX version 4.0 messages of message type “advertisement.”
