Re: [css3-speech] LC comment: use of generic SPAN element in voice-stress example and client-side use question

Hi Greg,
CSS2 provides [1] a sample user-agent default stylesheet for HTML4, which obviously is informative (as you rightly pointed-out, CSS is markup-agnostic).

I considered adding a similar appendix for CSS3-Speech, but I should think that modern HTML5 would be a better candidate, which unfortunately means working with a moving target at this point in time. I also believe that this should be a concerted effort, which wouldn't really fit in the release timeframe for Level 3 of the CSS Speech Module.

This is something we should aim for during the next revision of the specification, which would allow time for the community at large to reach a consensus on recommended default speech values for HTML5 markup. In other words, I suggest to defer your proposal to include a " default user-agent stylesheet" informative appendix, and I would encourage a parallel activity to take place (e.g. within the realm of a W3C Community Group?).

Please let me know if this addresses your concerns for this round of editing.

Regarding your question #2, I suggest you take a look at the "cascade" definition [2], which unambiguously defines the resolution process of user-defined versus author-defined styles.

Regards, Daniel
