The extensive caveats in the notes to that section of TUS Annex #29 would need to be taken into account. Word boundary identification needs to be tailored for many languages, and the basic Unicode mechanism only aims to provide 'as workable a default as possible'. Words -- and syllables, which present similar issues for selecting appropriate text elements for styling -- are units of spoken language that may or may not be easily isolated as units in written language, depending on particular writing systems as applied to particular languages. In some systems, e.g. Thai, word selection is only possible with dictionary support. JH
