good way to go. If you want to take full control of the creation / 
configuration of elements you can configure an AdviceBinding. For more 
information and some examples, see:

Eclipse Help contents > GMF Developer Guide > Programmer's Guide > Runtime 
> Extensible Type Registry > "Binding Advice to an Existing Element Type"


For example you could overwrite 
"getAfterConfigureCommand(ConfigureRequest)". This way you get a hook to 
provide a more complex configuration. For example you could easily 
instantiate an element B when the configuration of A is requested. This 
again results in an configure request after B has been created, and so on 
..


A good example for an advice binding is the class 
"NotationViewDependentsAdvice".
