In theory, any oneworld member can issue any oneworld fare (eg, the AA RTW desk should issue an xAS13, even though it is impossible to have an AA operated flight on such a fare). In practice, it is some what different. There are agents that believe a technical limitation of the online tool (first operating carrier tickets) is a rule (I had a good rant at CX with that one a couple of years ago). Most airlines want an intercontinental/inter regional flight under their own code before they'll ticket.
