Hi, Jean-Claude-

| Does display="none" have an influence on the rendering of the audio 
| element ? As display="none" does not influence the execution of the
| animate* elements, an explicit mention about this would be welcome.
| 
| It may be necessary to introduce the distinction between aural 
| rendering and visual rendering in the SVG spec which only talks of the 
| "rendering tree" today. The term "rendering" may need to be defined.

That's an interesting use case. Personally, I think there should be fine
control over the audio-rendering, but for the present, I think that this
case is covered by the distinctions between "display='none'" (which
effectively removes the element from the active DOM, and thus should be
silent) and "visibility='visible'" and "opacity='0'" (which should keep the
element, but stop it from being visible, though visibility does seem to
toggle the element's ability to register events).

If this is reasonable, it should be made explicit in the Spec, so
implementors are consistent.

Regards-
Doug
