This seems like a viable solution - the question is whether this is a
problem that needs solving, its contingent priority, and whether we
yet have a complete description of the problem.
How is this used in the literature? What fraction of columns/values
in VO DBs/images/catalogs require this? Is there a need to support an
offset as well as a scaling factor?
In short, are there domain use cases for this?

An even better example :-)
