Description of problem: Due to the support for all amqp1.0 properties/headers, following new special properties were added: x-amqp-first-acquirer, x-amqp-delivery-count, x-amqp-to, x-amqp-absolute-expiry-time, x-amqp-creation-time, x-amqp-group-id, x-amqp-qroup-sequence, x-amqp-reply-to-group-id These fields do not have explicit accessors, so these fields must be set different way than the already existing ones. It would make sense to have unified way for setting the hearders/properties. It would be reasonable to allow setting all the fields using the x-amqp- type syntax (e.f. x-amqp-subject etc) in addition to the existing explicit accessors. At least for amqp1.0 defined headers/properties. Version-Release number of selected component (if applicable): qpid-cpp-*-0.22-29.el6 Actual results: x-amqp-<property> available only for subset of message fields Expected results: unified way for setting all message headers/properties
