UEB includes very little formatting. The biggest change to Formats 2011 will be updating the examples to conform to UEB. There WILL be some changes to the content as well...but the majority of BF2011 will not change. The BANA Formats Committee is about halfway through BF2011 with their review. The goal is to finish by the end of 2014, though that is a very lofty goal, and does not include the approval process by the BANA board. The sections I expect to change the most (in content) will be emphasis and footnotes, and that is largely due to the fact that those sections define symbols which may conflict with UEB symbols or symbol construction.
The UEB Codebook does not appear to use 7-5 indents for transcriber notes (3.27), but the notes appear to be embedded with the regular text format. Are we doing away with the 7-5 indents for transcriber notes? How about notes before a wide table?
