I expect this is a common operation (e.g. creation of orgCharts from
relational tables). XML would seem to provide a useful approach,
especially client-side (most humans don't read relational tables very
well). Excuse my ignorance, but is this a sufficiently generic application
that there are well-understood rules for it and is there scope for a
generic XML approach?
