.. include:: /../getting_started/vars.rst .. _section-Product-Tools611: RTI System Designer ******************* Old types no longer accepted in group_data, user_data, or topic_data field ========================================================================== Because of the fix described in :ref:`section-SYSD-959`, |SD| now only accepts ``xs:hexBinary`` values for the ``group_data``, ``user_data``, or ``topic_data`` field. Although |SD| accepts XML files that use the old format (by converting the fields to the new format), if you enter values in the |SD| application itself using the old format, |SD| will produce an error. .. figure:: ../../static/sysd_type_error.png :figwidth: 50 % :alt: System Designer Old Notation Error :name: SysdOldNotError :align: center XML file from 6.1.1 may not load in previous releases ===================================================== In release 6.1.0, the ```` element was missing and has been added to the Presentation QoS Policy in |SD| in 6.1.1. Therefore, this element is not recognized by |SD| in 6.1.0 or earlier. As a result, an XML file created in |SD| 6.1.1 won't load in |SD| 6.1.0 if the ```` element is in the file.
