[OSM-talk] Tagging areas

[David Groom]

I'd like some advice on tagging areas.  Say for instance there is a park, 
bounded on four sides by roads, each or the roads is one way, and so the 
segments have to be drawn in the following order:

------>A-------------->B------->
            ^                       ^
             |                        |
             |                        |
             |                        |
             |                        |
------>C-------------->D------->

The park would be represented by the square with points at nodes, A, B, C & 
D.

Ideally I would mark the area as a way consisting of segments A-B, D-B, C-D, 
and C-A.

However according to the wiki 
http://wiki.openstreetmap.org/index.php/Editing_Standards_and_Conventions#Tagging_Areas 
"ensure that all the segments are drawn in the same direction".

If an area is marked as above then when it is rendered the fill is OK, ie 
all the square is coloured, but the stroke (the line which should border the 
square), not only borders the square, but also gets drawn from C-D.

Now I suppose the solution is to put in new nodes close to B, D & C and draw
segments which do all go in the same direction.  But this seems to be adding 
in a lot of unnecessary nodes and segments.  My understanding is at some 
stage anyway segments will disappear, and so all these "extra" nodes and 
segments become almost redundant anyway.

Is there any benefit to dropping the stroke rendering from the rules, and 
allowing areas to be defined as above?
