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

[Anders Torger]

For reference, here's Rijmmoáhpe again, a wetland which is about 4 km 
across, consisting of both bog and marsh:

It's located in Muddus national park, Sweden.

I'm quite sure the recommendation Christoph refers to is simply to put 
names on each separate part, which is seen in the screenshot. It's 
unclear to me if this is seen by Christoph and others as a final and 
good solution, or just as "the best we can do for the moment". So I hope 
to get a clarification on that.

Personally I see it as "the best we can do for the moment", but think 
that it of course should be rendered as a single name, and as such the 
name tag should not really be on each separate part, but on a relation. 
Sure a renderer could trace around and scan for neighboring areas with 
the same name and automatically, calculate the area of each part to find 
out the dominant nature type (required for name tag styling), and place 
a single name, but to me it does not seem like a proper way to arrange 
geo data for a single named natural entity.

So what I have done in addition is to create a relation with 
type=natural; natural=wetland; name=Rijmmoáhpe with all the parts as 
members (role field unset). If that is just too controversial, I can 
skip that and leave with just naming the parts. I planned to do that at 
first, but as some of these natural features are quite heavily 
fragmented in small pieces just for a management point of view in JOSM I 
found this relation to be practical thing to have, so I added it.

There's a whole family of unanswered questions regarding to names of 
nature. If Martin's fuzzy area concept was accepted and used 
https://github.com/dieterdreist/OpenGeographyRegions maybe many of these 
features would use that instead. Or maybe if place=locality concept on 
points was developed and diversified that could be used instead. I don't 
have any strong opinions on which method to use, I just want to be able 
to map with high detail and high quality and use any method that works.
