Currently you need to know to dig all the way into one of the quantity type aliases (e.g. Acceleration) or view the documentation for one of the types in the uom::si::fmt module (e.g. Arguments). Add additional module level to uom::fmt and uom::si::fmt (verify this doesn't break generated code for systems besides si) as well as update uom::fmt::DisplayStyle to include an example or explicitly link to one of the above locations.
