I think you're trying to solve several problems at the same time here. It
fails my 10-minute rule: I never spend more than ten minutes answering a
question on this list. Essentially both the para output and the list of
citations are grouping problems that can be tackled using
xsl:for-each-group, probably using group-adjacent. You may need to write a
function that calculates the grouping key. The suffix "a", "b" etc can be
obtained using xsl:number. It may be simplest to start by generating a copy
of the bibliography in which the list of authors (Doe and Jones) and the
year/serial (1999b) appear as additional computed child elements or
attributes, and then working with this copy.
