Hmmm--took me a minute to see the boolean(@container) in this line:

<xsl:for-each-group select="*" group-adjacent="boolean(@container)">

So that has the effect of creating a group for each continguous sequence of
contained things, which is certainly a characteristic I can impose on my
data (I control both the set of named styles and how they map to the
annotations added the <p> elements in the data being processed).

Given that, I think I should be able to process the group of contained
things with recursive for-each-groups.

Thanks,
