It would seem Andy that the 'rules' changed while we were not looking. It seems 
now that we should be tagging all roads :(

"For roads signed using the national non-numeric speed limits signs it is 
generally recommended that one also adds GB:motorway, GB:nsl_dual or 
GB:nsl_single to source:maxspeed=*."

I certainly don't agree with that. It will add a vast raft of extra tags to the 
road way data since they will have to be added to every link road and bridge 
section. JUST tagging the variations still in my book the way to do this and the 
router algorithms apply the correct speeds based on the type of vehicle.
