Its great that you are looking into this and writing some code. Over a year ago I created the Maplint tool (see http://wiki.openstreetmap.org/index.php/Maplint) but stopped working on it, because it was using the wrong approach (XSLT). Doing this with SQL is a lot better. You can look into Maplint and the JOSM Validator plugin (http://wiki.openstreetmap.org/index.php/JOSM/Plugins/Validator) for ideas on which checks to implement. Can we see your tool in action somewhere?
