+/*
+ * Reference:RFC 6020.
+ * The "leaf" statement is used to define a leaf node in the schema
+ * tree. It takes one argument, which is an identifier, followed by a
+ * block of sub-statements that holds detailed leaf information.
+ *
+ * A leaf node has a value, but no child nodes in the data tree.
+ * Conceptually, the value in the data tree is always in the canonical
+ * form.
+ *
+ * A leaf node exists in zero or one instances in the data tree.
+ *
+ * The "leaf" statement is used to define a scalar variable of a
+ * particular built-in or derived type.
+ *
+ * The leaf's sub-statements
