This is a feature of JBuilder Professional and Enterprise.
JBuilder provides several features and tools to support development of applications using the Extensible Markup Language (XML). A platform-independent method of structuring information, XML separates the content of a document from its structure. XML can be used to exchange data between databases and Java programs.
