Hi Harri,

> I'm not sure if I have the right to vote here,

As far as adopting this document goes, all opinions count.

> but as an employee of a global weather and environment sensor manufacturer, I strongly suggest that the following units are added into the secondary unit registry:
> 
> 1. mm/h (millimeters per hour, scale 1/3600000): This is a standard unit for rain intensity. The primary unit m/s is very awkward to use and results a very small floating point number.
> 2. ppm (parts per million, scale 1/10000 of %): Standard unit for mass fraction e.g. CO2 concentration in air  
> 3. hPa (hecto Pascal, scale 100 of Pa): Standard unit for air pressure.
> 4. mm (millimeter, scale 1/1000 of m): Standard unit for rain accumulation.
> 

this is good feedback for the authors, and I take it that then the
subregistry is needed. IMO the authors can probably add those units after the
document is adopted and before submitting the WG document version.
