I've posted revised draft of the spec r21 (has changes to DFDL Standard Character sets per call today) I also made corrections to dfdl:byteOrder - added missing binary booleans as one of the things byteOrder applies to, and removed sequence, choice, group from things that can carry the byteOrder property. Having done these fixes I realized this probably requires an erratum actually. r21 is at http://redmine.ogf.org/dmsf_files/13318 I've posted bit-order-features 3.1. This is http://redmine.ogf.org/dmsf_files/13317 Language revised to make bitOrder more primitive than byteOrder - applies to all grammar regions. Also added implicit-aligning to byte boundary on a bit-order change.
