The DDS_DomainParticipantResourceLimitsQosPolicy::local_type_allocation resource-limit limits the maximum number of unique ::DDSNDDS_Type_Plugin's that can be registered locally within a single DDSDomainParticipant with the FooTypeSupport_register_type() API. When a ::DDSNDDS_Type_Plugin is registered a string equal to the length of the type name in bytes plus one is allocated.
