Just for your information, there is also this "level:ref" tag which was 
used in various context to solve this problem :

- level tag is still used as defined in Simple Indoor Tagging
- level:ref has a value which is linked to operator naming of levels

That way, casual mappers/consumers don't need to stick to level 
definition which doesn't make regarding operator naming, they can set 
level:ref according to what they are used to see. And we keep the level 
definition which makes more sense for tools.
