// @brief PID_CONTENT_FILTER_PROPERTY (0x0035) discovery struct + CDR codec
//
// This header intentionally carries only the OMG-defined discovery
// datatype and its serialisation helpers so it can be included by
// layers (RTPS transport, DCPS Subscriber) that must NOT pull in the
// DDSSQL filter engine (which defines FilterValue / FilterOperator /
// LogicalOperator symbols that collide with ContentFilteredTopic).
//
// Reference: RTPS 2.5 §8.7.3.1, §9.4.2.11, §9.6.4.1
