You seem to have missed the "if needed" :-)

I know that it would be a pain to have to follow all the switch 
statements, but unfortunately I am afraid that is going to be anyways 
the case because the NX_detector group on its own is too broad because 
it covers 0D, 1D and 2D detectors. Of course this is just my opinion and 
I exposed it on last NIAC where I gave a testimonial vote in a 
discussion concerning the NXdetector group.

I put all my hope about getting something useful out of NeXus on the 
application definitions. Therefore I do not provide excessive relevance 
to *where* the data are. *What* the data are is a completely different 
history and things like pixel size and exposure time should mean the 
same for every 2D detector.

Best regards,

Armando
