WIA Device Information Property

Hello,
I am trying to implement a WIA minidriver for a scanner.
Can anyone please tell me whether it is OK to initialize driver item
properties leaving all Device Information Property Constants unused? Does a
WIA aware application expect values to be available for Device Information
Property Constants?
TIA
bkb
