Dear Bjoern,

this is a response to your comment at:

The playbackOrder attribute is only a hint to the user agent to  
indicate whether the author believes that seeking back in the  
timeline is likely to produce meaningful results or not. Setting it  
to "all" does not guarantee that when seeking back in time the same  
animation will be replayed since DOM manipulation may have altered  
the tree, and certainly does not require that the tree be reverted to  
the state in which it was at a given point in time.

When setting it to "forwardOnly" the author indicates that she  
doesn't believe seeking backwards will produce a useful effect,  
probably because DOM manipulations have largely altered parts of the  
tree required in past animations or because the discard element has  
been used to remove them entirely. It is therefore recommended that  
the user agent expose that information through its user interface.

Thank you for your thorough review, please let us know shortly if  
this does not address your concerns,
