 * Notes on deleting unsupported entities:
 * 1. PROTO: PROTO ProtoName [parameter list] {body}
 *      the parameter list will always have '[]'. So the items
 *      to delete are: String, List, Body
 * 2. EXTERNPROTO: EXTERNPROTO extern protoname [] MFstring
 *      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
 * 5. Script: Script { ... }
