Ok have updated all this.  Now the class will use the following preference
order in the _export() function, that is called by both exportToFile() and
exportAsXml().

1) The xmlHeader you supply as an argument
2) The xmlHeader that it parsed at import time
3) A default of <?xml version="1.0"?>

I presume this is what we want?  If not please get in touch.

I forgot to try to reproduce this before I made the fix, and now can't
reproduce it, so I presume that I fixed it on the way.  If not then I'm sure
we'll find out some time...
