you can set these attributes in inkscape via the xml-editor (ctrl+shift+x).
attributes are inherited from groups + layers, no need to add them to each shape
what it does not
handle nested <svg> elements
automatically scale the resulting map to usable dimensions
1 'mapsize' unit (using default scaling=2.0) corresponds to 14 SVG units
use the scale parameter here or later in the map editor to adjust
a midsized CTF map would have SVG dimensions of around 200 x 60
