* delete: string, string, string, list, list
|
|
|
|
|
* 3. Unsupported node types: NodeName (Optional DEF RefName) {body}
|
|
|
|
|
* This scheme should also apply to PROTO'd node types.

* 4. ROUTE: ROUTE nodename1.event to nodename2.event
|

* Delete a String 3 times

// possible for the BASE node to have reference nodes, for example:

// DEF BLAH Transform{}

// USE BLAH
|

// The code must be adjusted to respond to unlink requests and addNodeRef requests
