The example I provided doesn't write anything to a file. xml_schema::buffer
is a simple memory buffer abstraction (it is used for base64Binary and
hexBinary built-in XML Schema types). The example shows how to serialize
the object model into a dynamically expanding memory buffer and then read
from it.

If you want to read/write from/to a file, simply change the overflow()
function to write to a file and the underflow() functions to read from
a file. You can pass the file descriptor as the first argument.
