If you need sequencing, you should not use JMS at all, as order of devivery of
messages is "not significant" (to quote [4.4.12]).

This flag could hardly be enforced because delivery of messages can become quite
complex (for example, a consumer might receive old messages sent from a persistent
topic, or higher priority messages can jump ahead lesser priority ones).
