I investigated this a bit and it appears this is not about the validity
of the file but rather about the URI scheme (e.g., http://, file://, etc).
For some reason, XInclude implementation in Xerces-C++ does not like it
when you have a relative path as system id. That is, if I try to use
/tmp/test.xml, everything works but if I use just test.xml, I get the
above error. I have filed a bug report about this:

https://issues.apache.org/jira/browse/XERCESC-1879

One way to work around this problem is to use the LocalFileInputSource
class provided by Xerces-C++ instead of fstream. Internally this class
makes all relative paths absolute. I have updated your test to show how
to do this:
