This does not satisfy me. Clearly, the various language bindings are
derived from the IDL module name so e.g. for Java the svg module is
mapped to org.w3c.dom.svg, the events module is mapped to org.w3c.dom.
events and the smil module is mapped to org.w3c.dom.smil. In SVG 1.1
and SMIL Animation the TimeEvent is org.w3c.dom.smil.TimeEvent, so
putting it into the events module would mean one of

  * redundant interfaces (both .smil.TimeEvent and .events.TimeEvent)
  * inconsistent IDL to binding mapping ("events" would map to "smil")
  * SVG 1.2 is incompatible with SVG 1.1 and SMIL

and "makes more sense" is not a sound technical justification for any
of these. SMIL Animation is also sufficiently normative and maintained
to reference it from other sections of the draft, so I stand by my
original request.
