2. This may be able to be done already but I could not see how, currently I use my own style files to create the output I desire but every time a new feature is added the the default ones I need to get that and add to all my style sets or reapply my changes to the default ones. It would be good to have the ability to create a set of overide style files that only contain things that are to be changed from the default style you are using and some type of marker so some default ones can be deleted.
It's been suggested before that the style files have some sort of #include directive. As an example. We have a style called 'pedestrian'. The style rules file ./pedestrian/points would have a line at the top that said: #include ../default/points This would mean that the file ./pedestrian/points would include all the default points style rules. Below the #include directive in the ./pedestrian/points file would be: a) additional style rules not present in ../default/points b) over-rides (i.e. style rules that match the same OSM objects as ../default/points, but do something different) This would mean you could keep your own styles fully up to date with changes to the default style, and save you re-writing lots of rules that you don't want to change from the default. -- Charlie
