P1394> 1284 Device ID rules?

At the last Copenhagen meeting, we agreed that the descriptor that
follows the "LU entry" should conform to the 1284 Device ID rules.

As far as I remember, the above "1284 Device ID rules" did NOT include
the definition of the new keys, "CLASS" and "CLASSINFO", that was
introduced as a result of PnP off cycle meeting at Redmond.

I would like to confirm on what we agreed in order to aviod any further

Peter, is my understanding the same as what you proposed?

I think any new keys should not be defined without superceding original
IEEE 1284 specification because it already allows to create any key for
the implementations and any new key may conflict with such an
implementation defined keys.
