"Internally, the object model representing the domain configuration for a standalone server may be quite similar to that shown above. However, the XML configuration schema and perhaps the management API will be simplified to remove extraneous concepts like the ServerGroup. (Whether creating a distinct management API for this use case is appropriate needs discussion. A separate API means clients like JON and the embedded console need to be coded against two APIs in order to cover all use cases.)"

Creating to API's doesn't make sense at all. Instead we should try to collapse the concepts when used standalone. I.e. by referencing a default server group "standalone".
