As far as I remember, we decided that we build hyphenated techniques out of
base techniques, so your assumption is correct.

This is the difficult point about chromatography: the multitude of
different detectors. I think the cleanest approach would be to make each
detector a different technique (or maybe technique extensions). This would
require to put the UV, ELSm NCLD data into different ExperimentSteps.

Each detector-specific ExperimentStep would have a Reference element
pointing up the tree to the mother element, and would possibly sit in a
subordinate ExperimentStepSet of the mother page.

I see your point here. We need to put up guidelines for users how to
structure hyphenated data.
