Hi,

I think it is better if the construction of this new standard name is 
similar with the construction of other ones.

Of course we can discuss if we want to change all the existing 
from/to_direction standard_names, but it may take a lot more time to 
reach an agreement (On my side, I don't really have an opinion on the 
subject. from/to_direction may not be the best construction, but I think 
it is clear about what it represents)

I hope that, for the moment, this discussion won't prevent the creation 
of this new standard_name !


Best regards

Stéphane Tarot
