org.apache.lenya.xml.NamespaceHelper
A NamespaceHelper object simplifies the creation of elements in a certain namespace. All elements are owned by a document that is passed to the {@link #NamespaceHelper(Document,String,String)} constructor or createdusing the {@link #NamespaceHelper(String,String,String)} constructor.
