Hi Fabio,
You aren't setting namespace awareness to true on the
DocumentBuilderFactory. Both schema validation and XInclude require
namespace support. Assuming your schema actually contains an element
declaration for "NFe", I imagine setting namespace awareness would make it
work.
Note that you're not actually using Apache Xerces.
com.sun.org.apache.xerces.* classes are part of Sun's three year old fork
off the Xerces codebase. It has bugs which are unique to it and others
which have long been fixed in Apache so you may run into problems which
users here have never experienced (and never will experience).
Thanks.
