/* ConfigurationLoader doesn't need its own validator,

 * nor does it need to use the ConstructingParser which is used for TDML only because

 * it deals with CDATA nodes differently than the regular loader (DaffodilXMLLoader,

 * which is based on scala.xml.XML's loader, which is based on the sax parser

 * built into the JVM (which is xerces?), and which validates.

 *

 * For the configuration loader, we only need plain old loading.

 *

 * I suspect this was just cloned from the TDML loader code, and so copied its

 * more complicated arrangements.
