Across the editions

Each edition of XFS 3.x has one part per device class. The table lists the editions that have a part for Item Processing Module and, for each, how many queries, commands and events the part defines. A dash means the edition has no part for this class.

Source: the message tables of each edition's document. Queries are the WFS_INF_ messages, commands the WFS_CMD_ messages, events the service, execute, user and system events.

How to read the numbers

In XFS 3.x an application asks a device about itself with a query (WFS_INF_… – status, capabilities, the forms a printer knows), makes it do something with a command (WFS_CMD_… – print, dispense, read a card), and learns about things that happen on their own from an event (a card taken, a door opened, a threshold reached). The counts above are taken from each document's message tables, so they show how the class grew from edition to edition. A count that does not change does not mean the messages did not: fields are added and meanings refined within a message, and that is not counted here.
