The SMIL 2.0 spec defines this behavior with an additional attribute for
children of the excl time container.  Perhaps the pause method (when we
formalize it) should be extended to take a parameter equivalent to the
attribute.  Basically, it just controls whether the element is
rendered/applied while paused, or not.

IE 5.5 does not implement this attribute (IE had to go out ahead of the
spec, and so is missing some things like this that were added late). I just
wanted to be clear that the problem is not in the SMIL 2.0 spec, just in
this early implementation.

Good suggestion for v.next, as noted.

All these are supported by an experimental DOM implementation for SMIL in IE
5.5, as I mentioned before. In fact, you can even animate the speed, so you
do not need script.

DOM work for SMIL 2.0 (and thus for SMIL Animation) is ongoing, but will not
release with SMIL 2.0.

It would be inappropriate for SVG to add this kind of functionality to this
version, but I am sure we will continue to talk about it for future
