| 26 | * @summary Endpoint hostnames should always be fully qualified or |
| 27 | * should be an ip address. When references to remote |
| 28 | * objects are passed outside of the local domain their |
| 29 | * endpoints may contain hostnames that are not fully |
| 30 | * qualified. Hence remote clients won't be able to contact |
| 31 | * the referenced remote obect. |
