cvs commit: xml-xerces/java/src/org/apache/xerces/impl/xs/dom DOMParser.java DocumentImpl.java ElementNSImpl.java

sandygao    02/02/15 08:54:29

  Added:       java/src/org/apache/xerces/impl/xs/dom DOMParser.java
                        DocumentImpl.java ElementNSImpl.java
  Log:
  DOM implementation internally used for schema traversal.
  The only difference is that we store line/column numbers in element nodes.
