* </tbody> * </table> * * <p>The following paragraphs describe the namespace and prefix repair algorithm:

* * <p>The property can be set with the following code line: * <code>setProperty("javax.xml.stream.isRepairingNamespaces",new Boolean(true|false));

* * <p>This property specifies that the writer default namespace prefix declarations. * The default value is false. </p> * * <p>If a writer isRepairingNamespaces it will create a namespace declaration * on the current StartElement for * any attribute that does not * currently have a namespace declaration in scope. If the StartElement * has a uri but no prefix specified a prefix will be assigned, if the prefix * has not been declared in a parent of the current StartElement it will be declared * on the current StartElement. If the defaultNamespace is bound and in scope * and the default namespace matches the URI of the attribute or StartElement * QName no prefix will be assigned.</p> * * <p>If an element or attribute name has a prefix, but is not * bound to any namespace URI, then the prefix will be removed * during serialization.</p> * * <p>If element and/or attribute names in the same start or * empty-element tag are bound to different namespace URIs and * are using the same prefix then the element or the first * occurring attribute retains the original prefix and the * following attributes have their prefixes replaced with a * new prefix that is bound to the namespace URIs of those * attributes. </p> * * <p>If an element or attribute name uses a prefix that is * bound to a different URI than that inherited from the * namespace context of the parent of that element and there * is no namespace declaration in the context of the current * element then such a namespace declaration is added. </p> * * <p>If an element or attribute name is bound to a prefix and * there is a namespace declaration that binds that prefix * to a different URI then that namespace declaration is * either removed if the correct mapping is inherited from * the parent context of that element, or changed to the * namespace URI of the element or attribute using that prefix.</p> * * @version 1.2 * @author Copyright (c) 2009 by Oracle Corporation.
