Nino, Cool stuff, I look forward to taking a look. Also, nice that you are working with git-svn and mapnik_utils. Maybe we could even move mapnik_utils to github to make sharing code easier...

Using XML entities is great, but it's a bit hokey. I've implemented a solution that scratches our itch, but I thought I'd proffer it to the community. In a nutshell: 1) Define data sources and their SRS separately from layers (parse using python ConfigParser) 2) Layers refer to a data source by name 3) Support variable substitutions through the config parser's builtin mechanism 4) Allow for overrides of datasources and substitution vars (like settings.py and local_settings.py in django) 5) Compile .mml to .xml This makes cascadenik mml more MVCish: .mms == view, .cfg == model, .mml == controller Example: http://github.com/umidev/mapnik-utils/commit/806cfd75eb3774d27bf7a4a2e2e0f0621edec695 Implementation: http://github.com/umidev/mapnik-utils/blob/806cfd75eb3774d27bf7a4a2e2e0f0621edec695/trunk/serverside/cascadenik/cascadenik/source.py http://github.com/umidev/mapnik-utils/blob/806cfd75eb3774d27bf7a4a2e2e0f0621edec695/trunk/serverside/cascadenik/cascadenik/compile.py#L536 This was done quickly; not lots of comments in code, but not a lot of code.
