There are no extensions to the param element, although the param element
is indeed used in other sections.

As section 9.2 Timeline Initialization says
http://www.w3.org/2004/CDF/specs/CDR/wp-1/wicd.html#timeline-initialization

  Frozen and static renderings have no timeline and thus cannot be
  started and stopped.

If they have no timeline then, clearly, animations in that timeline cannot
be started and stopped either. The CDF WG discussed this on todays
telcon and believe the specification is already clear on this point.

Please let us know within two weeks if you disagree with this resolution.

Please review the current specification, which we believe already has
the normative wording you request. Specifically, it says:

With the "animation" parameter set to "onfocusevent",

    * the child content must render the first frame for time zero (0).

    * If the root element does not have focus, then the root element
      must then be paused at time zero(0).

    * Upon receiving focus, the root element is resumed.

    * Upon losing focus, the root element is paused.

After discussion, 'is' will be replaced by 'shall be' in the third and
fourth bullets.

Please let us know within two weeks if this revised wording does not
satisfy your comment.
