This change wouldn't affect the public API. SNS would still be supported as they are done now. Maybe with a few changes, but all within the JCR 2.0 specification. About compatibility: existing repositories would need to be converted in some way, that's true. One way to convert is the repository copier tool: http://wiki.apache.org/jackrabbit/BackupAndMigration Regards, Thomas
