Hi,

Following up on my previous question, would it be correct to nest <par>
tags used simply as a grouping mechanism?

For example,
<par>
	<audio ....>

	<!-- pseudo grouping 1 -->
	<par>
		<image begin="0" dur="3"...>
			<transitionFilter.../>
		</image>
		<animation begin="0" dur="3"...>
			<transitionFilter.../>
		</animation>
		<text begin="0" dur="3"...>
			<transitionFilter.../>
		</text>
	</par>

	<!-- pseudo grouping 2 -->
	<par>
		<image begin="2" dur="3"...>
			<transitionFilter.../>
		</image>
		<animation begin="2" dur="3"...>
			<transitionFilter.../>
		</animation>
		<text begin="2" dur="3"...>
			<transitionFilter.../>
		</text>
	</par>

	...etc

</par>

So we have an audio stream playing in parallel with 'groups' of other
media items which are roughly in sequence, but written in parallel (by
the top level par tag) to facilitate transition effects between the
'groups'

I am evaluating the potential of SMIL as a data format for a project I
am working on and so I am interested in what the language allows. I
think some kind of generic 'group' item, or meta data group tag, would
be useful in situations like this, however, as there does not appear to
be one within SMIL, is the above the correct approach?

Thanks
