1) Can the user create a new Socket Binding Group in a standalone instance or in a domain? I can create new individual socket bindings, but the drop-down menu for the binding group in teh console shows only the main default group, and I can't see an "Add new socket binding group" button or interface. 

2) Will the standalone instance be able to use multiple socket binding groups at all? I tried to create extra <socket-binding-groups> like in the domain configuration XML but the inclusion of additional groups seem to breaks the server at runtime. Perhaps I'm doing something wrong. 

3) Are socket binding groups only for domain instances? I assumed a developer could create multiple groups (in the XML, CLI or via console) to have different presets for different development tests or projects (which seems useful). Is this the intention?
