The paragraph that reads:

"Unless you are doing a synchronous request-reply, you should avoid
grouping together a send followed by an asynchronous receive within a
transaction. There could be a long interval between the time a that a
message is sent and the related message is asynchronously received,
depending on failures or downtime of other processes that are involved. It
is more practical to group the receipt of a message with the send of
another message."

has been changed to:

"Grouping together a receive followed by a send within a single transacted
is useful. However, you should never group together a send followed by a
receive within a single transaction. If you are intending to do this in a
request-reply fashion, the result would be deadlock. The request message
will never get to the replier until the transaction is commited. The
requestor will wait indefinitely for a reply that will never arrive."
