This file uses the macro feature to create sets of socket options. A single set can be loaded by using the set's outer config as a macro. In this example, the sets are:

• SocketOptions_ImmediateClose
• SocketOptions_GracefullClose

A note on naming conventions within the XML file. The property names starting with a lower case letter are required properties that ISMFIX Engine requires. The property names starting with an upper case letter are macro value names and are not required by the engine.
