That could be added, but the scale/offset columns are often all that is needed.  Open for input here.

The base unit listed is / (slash), the unit we use for dimensionless quantities in senml. Iirc, it even says so.

Yes. I now think it does update 8428, as it allows the user of units defined in the secondary table where 8428 only allowed the primary one.

That is a requirement on the DE already in 8428, so I'm not sure the is a new one here.

Thanks for the review. 
Do you think any of this blocks a WGLC?
