[Tagging] Extremely complicated conditional values

[Tobias Zwick]

Even shorter, because if there are conflicting rules in the conditional, the last one is taken, says the wiki. (Not sure if this is really implemented in applications that work with that data though):

maxspeed:advisory:conditional=37 mph @ (weight>=60000 lbs);26 mph @ (weight>=65000 lbs);22 mph @ (weight>=70000 lbs);18 mph @ (weight>=75000 lbs AND weight<=80000)

Notes:
- I'd always specify units as they are used on the sign for better confirmability
- to be precise, I guess you'd need to add "AND axles>=5" in every conditional
