+/*-
+ * Reference RFC 7950.
+ *
+ * The "anydata" statement defines an interior node in the schema tree.
+ * It takes one argument, which is an identifier, followed by a block of
+ * substatements that holds detailed anydata information.
+ *
+ * The "anydata" statement is used to represent an unknown set of nodes
+ * that can be modeled with YANG, except anyxml, but for which the data
+ * model is not known at module design time.  It is possible, though not
+ * required, for the data model for anydata content to become known
+ * through protocol signaling or other means that are outside the scope
+ * of this document.
+ *
+ * An example of where anydata can be useful is a list of received
+ * notifications where the specific notifications are not known at
+ * design time.
+ *
+ * An anydata node exists in zero or one instance in the data tree.
+ * An implementation may or may not know the data model used to model a
+ * specific instance of an anydata node.
+ *
+ * Since the use of anydata limits the manipulation of the content, the
+ * "anydata" statement SHOULD NOT be used to define configuration data.
+.*
+ * The anydata's Substatements
+ *
+ *               +--------------+---------+-------------+
+ *               | substatement | section | cardinality |
+ *               +--------------+---------+-------------+

+ *               | if-feature   | 7.20.2  | 0..n        |
