Dear all,


In the 3 test of SVG Tiny 1.2 animate-elem-20-t, animate-elem-21-t and
animate-elem-29-t [1], it is said:


"With the second click on "fade in", however, the behavior might be
different. [...] After the second click on "fade in", however, the red square
goes from zero to 100% opacity, and then goes back from 100% to zero opacity.
This is because of the hyperlinking rules as they relate to resolved start
times in the SMIL 2.1 specification."


is this behavior normative ? or is it only one of the possible behaviors and
the might still pass if the fade (in/out) only respond to mouse clicks.


If this is a normative behavior, can somebody point out the part of the SMIL
specification describing this behavior ?


If this behavior is normative can somebody clarify the behavior in the
following case:

- 0s: Click on "fade in"  -> Fade in starts

- 3s: Click on "fade out" -> Fade out start

- 7s: Click on "fade in" -> Fade in start

- 10s: No actions          -> Fade out (might) start (as described in the
test case)

- 14s: Click on "fade in" -> Fade in starts

- 15s: Click on "fade out" -> fade out starts (I would expect it)

- 20s: Click on "fade in" -> Fade in starts


-> When will the fade out start ? 1s latter ? 3s latter ?  

Opera is starting the fade out 3s later, but I must admit I cannot see any
explanation for that.
