/**

 *
 * Highlevel Client Functionality
 * ------------------------------
 *
 * The following definitions are convenience functions making use of the
 * standard OPC UA services in the background. This is a less flexible way of
 * handling the stack, because at many places sensible defaults are presumed; at
 * the same time using these functions is the easiest way of implementing an OPC
 * UA application, as you will not have to consider all the details that go into
 * the OPC UA services. If more flexibility is needed, you can always achieve
 * the same functionality using the raw :ref:`OPC UA services
 * <client-services>`.
 *
 * Read Attributes
 * ^^^^^^^^^^^^^^^
 * The following functions can be used to retrieve a single node attribute. Use
 * the regular service to read several attributes at once. */
