Optional: because there are not "multiple Routing Keys and Routing Contexts
used accross a common association" and, therefore, the MUST does not apply.

As there is only one routing context for the entire association, the
implementation should not have a problem discerning that.  OTOH, an
implementation could choose to send one anyway (if one was even assigned).
