| - | This policy is considered a hint. The policy depends on the ability of the underlying transports to set a priority on the messages they send. Any value within the range of a 32-bit signed integer may be chosen; higher values indicate higher priority. However, any further interpretation of this policy is specific to a particular transport and a particular implementation of the Service. For example, a particular transport is permitted to treat a range of priority values as equivalent to one another. It is expected that during transport configuration the application would provide a mapping between the values of the TRANSPORT_PRIORITY set on ''DataWriter'' and the values meaningful to each transport. This mapping would then be used by the infrastructure when propagating the data written by the ''DataWriter''. | + | This policy is considered a hint.
