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.
