[Tagging] How to put a name tag on an area with more than one type?

[Anders Torger]

I'll make a small change to my naming strategy: use one multipolygon per 
natural tag set, and thus minimize the number of same-named polygons.

Normally, when naming entities which has all the same natural tags but 
separate areas, such as a couple of ponds or islets with a collective 
name (common), it's made as a single multipolygon with several outers. 
I've heard that there are renderers that actually already today then 
render a single text label.

As natural tags differ in this wetland a single multipolygon is not 
possible. However one can make one polygon per set of natural tags. For 
this Rimmjoáhpe wetlend I then get away with two multipolygons, thus 
greatly reducing the number of text labels rendered in some renderers, 
while still being compatible with the other method of keeping every 
adjacent polygon on their own.

It also makes it easier to keep all parts together when editing as a 
multipolygon is also a relation.
