OK. But what about situation when I have some service (let's call it service A) with ERPs A1 and A2. I want to replace this service by new version with different EPRs (A3 and A4). Of course it will work during "normal" server work. But what will happen in case when: 1. Start server 2. Deploy 1st version of service A (EPRs: A1 and A2) 3. Server crash 4. Replace service by 2nd version (EPRs: A3 and A4) 5. Start server Server will register EPRs A3 and A4, but what about old (incorrect) EPRs A1 and A2)? Registry doesn't know that registering A3 and A4 means registering service A again. If we have registerService method in Registry interface (for example with List of EPRs as parameter, or with only first EPR as parameter) we could delete incorrect EPRs in such case.
