-/**
- * An IStructuredDocument that performs most of its computation and event
- * notification through an IExecutionDelegate.
- * 
- * If the delegate has not been set, we execute on current thread, like
- * "normal". This is the case for normal non-editor use (which should still,
- * ultimately, be protected by a scheduling rule). For every operation, a
- * runnable is created, even if later (in the execution delegate instance) it
- * is decided nothing special is needed (that is, in fact being called from an
- * editor's display thread, in which case its just executed) in the UI.
