/**
 * This is a program to echo a DOM tree using DOM Level 2 interfaces.  Use
 * JAXP to load an XML file and create a DOM tree.  DOM currently does not
 * provide a method to do this.  (This is planned for Level 3.)  See the
 * method "main" for the three basic steps.  Once the application obtains a
 * DOM Document tree, it dumps out the nodes in the tree and associated
 * node attributes for each node.
 *
 * This program also shows how to validate a document along with using an
 * ErrorHandler to capture validation errors.
 *
 * Note: Program flags may be used to create non-conformant but possibly
 * useful DOM trees.  In some cases, particularly with element content
 * whitespace, applications may not want to rely on JAXP to filter out
 * these nodes but may want to skip the nodes themselves so the application
 * will be more robust.
 *
 *  Added code that shows how to use JAXP 1.2 features to
 * support W3C XML Schema validation.  See the JAXP 1.2 maintenance review
 * specification for more information on these features.
