Just a few remarks on this solution:

1. The above can be simplified because a document node's following::
axis is the empty nodeset:

     <xsl:for-each-group select=
      "descendant::processing-instruction()
                          [name()='pi-start']"
      group-starting-with="processing-instruction()[name()='pi-start']">

2. We take the assumptions that the pairs of "start", "end" PIs are
non-overlapping.
