[Timesheets LC comment] 5.2 Elements

Dear SYMM WG-

This is a Last Call review comment from the SVG WG on the SMIL 
Timesheets 1.0 specification, W3C Working Draft 10 January 2008, 
http://www.w3.org/TR/2008/WD-timesheets-20080110/ .  Please let us know 
if you have any questions by replying to www-svg@w3.org.


The explanations of the par, seq and excl elements seem informative. 
Please make them so, and add a normative statement saying that these 
elements are defined in the SMIL 3.0 Timing and Synchronization module.

---

"The excl element defines a time container with semantics based upon 
par,but with the additional constraint that only one child element may 
play at any given time."

It's not clear to the SVG WG whether this is a constraint added by 
Timesheets or by SMIL Timing and Synchronization.

---

"If any element begins playing while another is already playing, the 
element that was playing is stopped."

Please clarify what it means that "playing is stopped".  Is the timeline 
paused, reset, or something else?  What happens if the time first 
animation is started again?

What happens if an animation is running in one "slide", and the user 
navigates away, then returns?  What state is the animation in?



Regards-
-Doug Schepers, on behalf of the SVG WG
