Perhaps this problem could be clarified by considering the question of whose responsibility it will be to implement the audio component of CSS 2. I would submit that most of this work will ultimately fall to access software developers rather than browser vendors, since it is the access agent that is responsible for regulating the speech output. Thus, all that we need ask of browser developers is that DOM should expose (1) the full markup of the table, including the relationships established by the HEADERS and SCOPE attributes in HTML 4.0; and (2) the CSS 2 properties (such as SPEAKCELL and SPEAKROW) which are associated, as macros, with table rows. DOM would be the means by which this information is communicated to external software, and it would be the function of the access agent (which is an audio formatter in T.V. Raman's sense of the term) to produce the required audio rendering. Based on the negotiations in the CSS 2 meeting, do you think that it would be reasonable to expect macro capabilities to be implemented as far as the DOM stage, which is all that would seem to be required, according to the analysis carred out above?
