[xsl] Grouping using group-starting-with=

["G. Ken Holman" <gkholman@xxxxxxxxxxxxxxxxxxxx>]

Hi folks,

I'm using Saxon 8.8J and I'm trying to group a
bunch of sibling items into groups of items that
start with the item that has a particular child with a particular value.

It would seem that the following does not work:

    <xsl:for-each-group select="/*/Item"
                        group-starting-with="RepresentationTerm[.='Code']">

Looking at XSLT 2.0, group-starting-with=
requires the population to all be nodes, and
there are a number of nodes that match the
pattern test supplied ... yet running the example
I am only getting a single group ... which I
suspect is just the first node in the population.

I'm missing something obvious ... could someone
please point me to the correct chapter and verse?

I have my example below of test data and
stylesheet ... my real data has much more
information and more representation terms, but it should still be the same.

Thanks!
