Yes, it is.

No, each call creates a new parser.

You will need to call xercesc::XMLPlatformUtils::Initialize() and
xercesc::XMLPlatformUtils::Terminate() in your main() as well as
pass the xml_schema::flags::dont_initialize to the parsing function.

Xerces-C++ Initialize() and Terminate() are not safe to call from
separate threads and that's exactly what may happen when you call
one of the parsing functions from two different threads.
