Yes, see second part of my posting you responded to.

But the example does not support your original idea of defining 
maxweight (=*actual weight* restriction) for complete trains instead of 
vehicles. It only supports it for gross_weight, but this was already 
pointed out by me.


To focus back on the original topic:

What is your conclusion regarding the proposal and the tagging of these 
restrictions?

The crucial part is to keep tagging simple. We cannot expect that 
everyone knows the subtle legal differences (I didn't know them until I 
have done my own investigation). A trade-off between pure road-sign 
tagging (which makes interpretation difficult) and the meaning (which is 
complex due to vehicle, trailers, weight types, etc) is required.
