 One common requirement is the differentiation between the maximum size of received and sent datagrams.
 This capability is especially important in scenarios where a system might need to handle large incoming
 data sizes but should restrict the size of the data it sends to prevent overwhelming network resources
-or complying with network traffic policies. The primary attribute for controlling datagram size is
-`maxMessageSize`, which sets the upper limit for both the size of datagrams that can be received and
-those that can be sent. For applications that need to restrict the size of outgoing datagrams without
-changing the size of incoming ones, it's possible to set the new property ``fastdds.max_message_size``.
