You mean:

condition1=wet
maxspeed:lgv=120 or 80 in condition1

If we consider that a special parser is required as soon as one of the
keywords "condition", " or ", " and ", " in ", " not " is present in
the value, we could even reduce the amount of tags:

maxspeed:lgv=120 or 80 in wet

Or about one of the previous examples:

access=yes
motor_vehicle:forward=not (Mo-Fr 16:00-18:00)
motor_vehicle:backward=not (Mo-Fr 06:00-09:00)
