+/**
+ * @brief Data type for representing a D-Bus variant
+ *
+ * When D-Bus methods or signal require that a paramater can have any of the
+ * D-Bus data types, a D-Bus variant can be used.
+ *
+ * Basically a D-Bus variant includes the actual data and a D-Bus data signature
+ * to allow a receiver to determine the contents.
+ *
+ * Since the TQT_DBusVariant's #value member will already be fully de-marshalled,
+ * a receiver using this bindings can savely ignore the signature if it doesn't
+ * need it for a different purpose (e.g. logging).
+ *
+ * However, when creating a TQT_DBusVariant object for sending, make sure the
+ * #signature member is correctly setup, for example by using the #value
+ * member's buildDBusSignature() method.
+ *
+ * @code
+ * TQT_DBusVariant variant;
+ *
+ * variant.value     = TQT_DBusData::fromInt32(131719);
+ * variant.signature = variant.value.buildDBusSignature();
+ * @endcode
