[OSM-dev] Multipolygon decoding

Hello,
I am developing my own rendering software and I struggled on decoding 
multipolygon relations. It seems to be bit tricky. I tried to found some 
info about it, but all I found is this wiki page: http://wiki.openstreetmap.
org/wiki/Relation:multipolygon/Algorithm

Can you point to some example of code decoding multipolygons? I would 
especially like something that will be written with renderer in mind (ie 
source code is part of some renderer).

Note that my software decodes OSM XML file itself, I don't want to use 
PostGIS as backend.
