much to add in terms of the serialisation format (save I would personally
prefer an XML format without having academic argument for such a

XDM data - I thought that such a serialisation format could be to create
standard XPath/XSLT debugging dump that could be more tightly integrated to
the host language - e.g. using xsl:message, XPath trace(). Furthermore a
standard format could also give rise to portable unit testing frameworks
where assertions could be performed against the XDM serialised form or
provide a convenient way of saving mementos of processing state - as
