The message comes from the XML parser, not from Saxon - Saxon is only the
messenger, and tries hard to make this clear, but people still think it's
Saxon complaining.

I *think* that this message from Xerces usually means that a file has been
successfully read, but it's not XML, or anything remotely resembling XML. In
this case I suspect that the resource with URI "/" is a directory listing,
and Xerces of course can't parse a directory listing as XML.
