I am writing an application that will essentially display a slideshow
with audio (a grossly simplified description). I had intended to use
SMIL as the data format.

The presentation will consist of many animation items, roughly (see
below) in sequence, all played out in parallel to an audio track.
Associated with each image, or animation there may be multiple text
objects. My question is, how to arrange this within a SMIL document?

Many of the animations will require transitions between each of them. As
I understand it from the specifications, this requires the animations be
placed within a <par> block, and the timing data given to arrange the
overlapping effects. Using the <seq> element in this case for
transitions with fill=transition would 'freeze' the last frame of the
animation then perform the transition, which is not the desired effect.
Is using the <par> element the correct way to be looking at this?

Also, is there a way to group related items? For instance, the animation
and the associated text objects are related, however there is nothing to
relate these items specifically when all items (and there many be many)
are placed within the <par> elements as above.

Any help or guidance?
