6.2. Make SVG output a bit more editor friendly
SVG created by the CairoGraphics render backend is not really made for being post-processed by a vector graphics program like e.g. InkScape. The generated SVG is completely unstructured and does not really contain any grouping or layers.
To make things even worse any text output is done by emitting single character glyphes. So when trying to post process SVG results by moving some label texts around, you need to take care of selecting every character individually.
The Mapnik Group Text tool by Ilya Zverev. It finds letters and their casing in the generated SVG, tries to find words they form, and then groups the letters per word so that you can easily move words as a whole instead of individual letters.
