+/**
+ * Standalone wiring for RESTCONF.
+ *
+ * <p>ACK: Some lines here were originally inspired by the RestConfWiring class in
+ * opendaylight-simple which in turn was inspired by the CommunityRestConf class
+ * from lighty.io. The differences include (1) that this class is "pure Java"
+ * without depending on any binding framework utility classes; (2) we do not mix
+ * bierman02 and rfc8040 for proper modularity;  (3) we simply use {@literal @}Inject
+ * instead of manual object wiring, where possible.
