Then choose another browser that makes it easier for you to get the content. This aspect of the HTML spec. is describing a 'document' format, and what the elements in the document mean, in a sense. How the user-agent determines what its user wants -- by keeping preferences, by drawing inferences based on other expressed preferences, by asking lots of questions all the time, by showing everything it possibly can -- is really rather out of scope. For example, a document might say (somehow) "a transcript is available over <here>" and the user and UA are free to use that piece of information as they wish and why they wish. >That's why an automatic alternative selection chain isn't the (only) >place where a transcript should be put. I'm sorry if I implied that it should be. I was wondering about (not really even proposing) longdesc. I was also wondering about what should happen when an alternative selection chain fails to select anything; at the moment, the answer is nothing and it's an authoring problem to avoid that case. If the two got conflated, I also apologize! -- David Singer Apple/QuickTime
