+/*
+ * 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
