I'd like to suggest that the <dax:member> tag work like this: it iterates the members from the first (or only) disc, UNLESS it is enclosed within a <dax:volume> ... </dax:volume> pair, in which case it iterates the members of the current volume.

That would help the theme I'm slowly building work the way I want, because it would permit me to keep track of which disk and tracks each member contributed. With some Javascript, I can group them...

Thanks...
