Well, that depends on the design.  If SANE is HAL-aware, then yeah, just 
passing a UDI would be fine.  If not, then your API could be the wrapper 
that provides SANE with the details that it got from HAL.  (This is how 
libgphoto works, I believe.)

I see.  It sounds like a good idea to generate the FDI files from the 
SANE information, as was suggested by Abel earlier in the thread.  That 
should give you the info you need, right?
