The first thing is to send us a link to the schema that the
other application expects. That would give us a "one-to-one"
mapping; otherwise, data.frame to arbitrary XML is to vague.
Currently, there is nothing in the XML package that would
be able to take an XML schema and write an R object to such a
structure. However, I am in the process of creating an XMLSchema
package which can read XML schema and make the description available to
R so that we can read data from an XML file corresponding to that schema
and this could be adapted in some ways to automate the creation of
XML from an R object (under certain assumptions).
So please send us all a link to the XML schema.
