The XML Editor in NetBeans 5.5 is far improved. It includes XML schema tools that help you visualize and edit XML schemas. These tools are particularly effective for real-world use issues, because they offer scalable visualization and editing of very large XML schemas. You don't have to be a schema expert to create and modify XML schema documents. Using the author-by-example facility, you can greatly reduce the complexity of creating and editing XML schemas. In addition, you can find usages, refactor, and safely delete across XML schema, WSDL, and BPEL files.
