What is the target structure? The job of the converter is to take
something - in this case HL7 - and convert it to an equivalent XML
form so that generic transformation tools can be used.
There are lots of good tools for manipulating XML, but not so many
So for this reason, the converter does a 'simple' mapping of the HL7
file to something that can be transformed. Now, XQuery and XSLT are
excellent tools for rearranging data, so instead of making a converter
that does it all, with a high learning curve, we opted to make the
converters 'transparent' and use more generic technology to do the
The XML Converter will always produce XML that matches the schema we
generate from the same repository, so you don't need to do anything
there. We've done that part. It's what you want to do next that's
up to you.
