As of Weave 2.5.28 it's possible to include additional EPSG definitions via an epsi.properties file included in the workspace directory.

The file contents should include a single line definition per-projection in the format of <code>=<definition>, where <code> is the numeric EPSG code and <definition> is the OGC WKT projection definition. e.g.
