level=* should have numbers only with optional .5 increments

​Osmose, that uses the JOSM numeric validator, complains about level=0-4, but this tagging is allowed in the ​Simple Indoor Tagging: "Use a semicolon to separate the levels covered by the stairs, escalator, or elevator, or define a level range. For example, level=0;1 or level=0-1 could be used on some stairs that connect levels 0 and 1. Stairs connecting levels 2 and 4 would be tagged level=2;3;4 or level=2-4 – regardless whether level 3 can be accessed from these stairs."

So the validator should allow this tagging as well (at least with stairs, escalators and elevators).
