//  Hi Heather.  For the XML conversion service I defined an
//  extra interface to do generic XML things that converters
//  might need.  For now there really is just one thing there:
//  a function which reads in the XML file, so that the converters
//  deal with the DOM representation (in-memory, but otherwise 
//  isomorphic to the XML description) rather than with the physical
//  file.  Putting that kind of functionality in the conversion service
//  is probably a good idea, but it doesn't have to be defined in
//  an abstract interface.
