  13. * Highlevel Client Functionality
  14. * ------------------------------
  15. *
  16. * The following definitions are convenience functions making use of the
  17. * standard OPC UA services in the background. This is a less flexible way of
  18. * handling the stack, because at many places sensible defaults are presumed; at
  19. * the same time using these functions is the easiest way of implementing an OPC
  20. * UA application, as you will not have to consider all the details that go into
  21. * the OPC UA services. If more flexibility is needed, you can always achieve
  22. * the same functionality using the raw :ref:`OPC UA services
  23. * <client-services>`.
  24. *
