<background> Please refer to the 'ttm:role' attribute as defined in the curent Timed Text DFXP specification. http://www.w3.org/TR/2005/WD-ttaf1-dfxp-20050321/#metadata-attribute-role A caucus of WCAG and UAAG participants concluded that they might want an explicit 'transcription' value for such a role. http://lists.w3.org/Archives/Member/w3c-wai-cg/2005AprJun/thread.html#35 </background> <comment> User agents need clear indications in the format of what text corresponds to speech in some corresponding audio segment. This is needed in order for the User Agents to satisfy UAAG Checkpoint 2.3. http://www.w3.org/TR/UAAG10/guidelines.html#tech-conditional-content We realize that the DFXP will most often be transcoded into another format before transmission to the User Agent. However, in order for the transmitted form to have this information, the distribution format must be clear on this point for the transcoded results to convey the right information. Is this information recognizable from the existing format as it stands? If so, how? Or should the 'ttm:role' attribute have a value of 'transcription' defined? </comment> Al /chair, Protocols and Formats WG This comment has rough consensus support within the WG
