Right. In i1d3edr.c there is a hard coded equivalent to the 
TechnologyStrings.txt file that
maps the slot numbers to a more human readable description, and this is what 
gets listed
in the tool usage. I did contemplate parsing the TechnologyStrings.txt file 
but it would not always be available if translating individual .edr files, and I
ran out of time to implement it. The hard coded descriptions are a bit more 
too, I think.

Yes, it seems X-Rite have allowed for many display technology types that they 
by default ship .edr files for. I guess some of these slots may be filled in by
their Cinema OEM's.

Of course there is nothing to stop anyone making a bunch of .ccss files for any
of the above technologies if they have a spectrometer and a display to measure,
and I'm happy to make them available on the ArgyllCMS website.
