I've started contributing to InkScape in my own way, I have made a dent on a filter to sanitize InkScape.

• Wiki profiler page: Save_Cleaned_SVG
• islint at SourceForge

My motives are purely selfish. I'm one of the authors of SVG, I work with SVG, and I find that InkScape to be an excellent tool, but I spend a lot of time editing InkScape output with vi to clean it up for use in dynamic web apps (mostly). A task with very low entertainment value. Writing filters is more fun.

islint is pretty useful to me as it is, but it has a way to go before it will serve as a general filter for InkScape.

This is the wrong place to do this, but it will serve for now...
