Hi Eliot,

Yeah, sibling recursion was something we had to resort to before we had native grouping constructs, to allow XSLT to see structural relations where it only had contiguity.

These days, grouping-based solutions using group-adjacent, group-starting-with and group-ending-with are available; they are much easier to get one's head around and much much easier to abstract, generalize, encapsulate and maintain, which you are very much likely to want.

As a consequence, sibling recursion of the classic sort is hardly necessary in XSLT 2.0. Structural induction becomes a special kind of grouping problem.

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.
