Iceman,
That is specifically and only tp do with breakout instructions during a PRM ILS procedure. In all other cases, RA should be complied with with wings level.
HOWEVER, the response to a TA is "Manoeuvre as required". There is no TCAS instruction with a TA, and no limitation on lateral manoeuvring. Rules of the air still state that aircraft on a collision course should alter heading to the right, so I think a turn to AVOID an RA situation is an appropriate response.
