* defines a QoS profile named volatile_profile that configures reliable,
* volatile DataWriters and DataReaders.
*
* 2) Adding XML documents to the DomainParticipantFactory using its
* Profile QoSPolicy (DDS Extension). In this case, we add
* my_custom_qos_profiles.xml to the url_profile sequence, which stores
* the URLs of all the XML documents with QoS policies that are loaded
* by the DomainParticipantFactory aside from the ones that are
* automatically loaded.
* my_custom_qos_profiles.xml defines a QoS profile named
* transient_local_profile that configures reliable, transient local
* DataWriters and DataReaders.
