[Tagging] Tagging of topographic areas with a name

At the risk that this is mapping for the renderer, but what
Wolfgang proposes is exactly how it is done on traditional paper maps. It
gives you the possibility to label some loosely defined entity, by creating
some labelling along a non visible way.
However, there is a serious complication in this, which consists in the
fact that you would have to assign some kind of "importance" to the label
to allow the renderer to decide at which zoom levels to show the labelling
and with what kind  of visibility. So, if we want to go this way, the thing
is not quite as simple. We would need to define something like the
equivalent of admin_level, may be an importance_level.
Just my 2 cents - I admit this is not thought through in any way, but ...
