When using PDSOE, OE project types like 'REST' and 'ABL Web App' include deployment-specific and derived artifacts in the projects thus cluttering up when should be a source-only project.

Please consider creating separate project types (similar to creating a plug-in 'Feature' or 'Update Site' projects for Java plug-in development), with a wizard to create those projects.  This will appropriately separate the development and deployment application resources instead of having derived resources in source code projects.
