You can now put any style sheet elements you like inside <scale min='...' max='...'> ... </scale>: groups of layers, groups of conditions, individual tags, in fact anything you like, as long as tags are still nested properly. Anything that doesn't apply to the current scale is skipped when the style sheet is compiled, which happens when you change scale. The old syntax (<scale min='...' max='...'/>, with nothing inside the <scale> element) still works as before: it applies to the enclosing style. Use the new syntax if possible. It is more efficient and more flexible.
