/*-
 * Reference RFC 6020.
 *
 * The "augment" statement allows a module or submodule to add to the
 *  schema tree defined in an external module, or the current module and
 *  its submodules, and to add to the nodes from a grouping in a "uses"
 *  statement.  The argument is a string that identifies a node in the
 *  schema tree.  This node is called the augment's target node.  The
 *  target node MUST be either a container, list, choice, case, input,
 *  output, or notification node.  It is augmented with the nodes defined
 *  in the sub-statements that follow the "augment" statement.
 *
 *  The argument string is a schema node identifier.
 *  If the "augment" statement is on the top level in a module or
 *  submodule, the absolute form of a schema node identifier
 *  MUST be used.  If the "augment" statement is a sub-statement to the
 *  "uses" statement, the descendant form MUST be used.
 *
 *  If the target node is a container, list, case, input, output, or
 *  notification node, the "container", "leaf", "list", "leaf-list",
 *  "uses", and "choice" statements can be used within the "augment"
 *  statement.
 *
 *  If the target node is a choice node, the "case" statement, or a case
 *  shorthand statement can be used within the "augment" statement.
 *
 *   If the target node is in another module, then nodes added by the
 *  augmentation MUST NOT be mandatory nodes.
 *
 *  The "augment" statement MUST NOT add multiple nodes with the same
 *  name from the same module to the target node.
 *  The augment's sub-statements
