Most descriptor sub-trees can be copied and later pasted. Copies are always deep-copies: for example if you copy a node, all the servers on this code are copied, including all the the sub-elements of these servers (object adapters, database environment, services, etc.).
After pasting a sub-tree, you typically need to check and edit the new elements to avoid any duplicate server IDs, adapter IDs etc.
