Again, the latter suggestion works, thank you, but in truth I don't
understand this reference to the 'document element'. Could you point
to a relevant part of the specification that explains 'context node'
please?

I tried to the bind element reference to 'savepagegeneralinformation'
but that failed, so removed the bind element in the submission element
as you subsequently described.

My typing mistake, sorry.

I looked at the output file 'testsubmit.xml' which appears as:

<?xml version="1.0"?>
<generalinformation>
       <generalinformation/>
      </generalinformation>

This seems wrong to me; I was expecting the output to contain 'epc
england' if chosen from the list menu. Am I right to conclude that
this is a bug with writer?
