i might have a christmas present for you...
please have a look at the files below:
you could insert the *.osm in your original osm file and have a render
rule for those entries. then you can use a renderer of your choice, like
KOSMOS. Don't know if gpx is useful though.
and here's the code (you will need the modules too!) - first BETA. no QA
took place :-)
any more wishes?
ps: i don't know if shapes like elevation lines really make sense
pps: wiki page will follow!
