SVGAnimationElement.getStartTime

Hi,

I would like to revisit the specification of
SVGAnimationElement.getStartTime. As noted by Cameron McCormack in January
2006[1] the SVG 1.1 specification simply states that this method:

  Returns the start time in seconds for this animation.[2]

However, it does not specify which start time in the case of multiple start
times. Is it the start time of the current active interval? And if there is
no current active interval is it the start time of the next interval or the
previous interval?

I have produced a small test of this behaviour[3] and note that Opera 9.62
appears to return the start time of the current interval, or failing that
the start time of the next interval, or failing that the start time of the
previous interval.

I think it is necessary to define this behaviour more adequately.
Unfortunately Cameron McCormack's previous query went unanswered. Is it
possible to add an erratum specifying this behaviour?

Best regards,

Brian
