The SVG Tiny 1.2 Working Draft does not unambiguously define the default
event base element for event based timing of the <audio>, <video>, and
<animation> elements. The only way to address that problem is by making
changes to the normative text of the draft, or its normative references.
The Working Group does not agree with making such changes, therefore it
is incorrect to claim the Working Group agrees with my request.

It is incorrect to include such text without having normative text that
actually reflects what is stated here. Once the Working Group includes
the normative definitions I have asked for, there is no need for such
informative text to exist and it is indeed a bad idea to include it. The
text would already be unacceptable for the reference to SMIL Animation,
which is not an adequate normative reference for SVG Tiny 1.2, as the
SVG Working Group informed me.

You've already explained why the very idea is ridiculous by providing
at least two mutually exclusive interpretations in this thread.

I encourage you to simply count the number of issues raised on this list
to which there was no response whatsoever before making such claims.
