There is a customization wizard available for creating XML files. It is invoked from the "New" menu, when choosing the "XML" type. This dialog asks for an XML Schema or DTD. After chosing the proper URL (for XML Schema) or SystemID (for DTD) you will get a drop list of possible root elements for your document. Chose one of them and start editing by pressing the "OK" button.
Note: If you do not select a schema or DTD location, or the document root is not specified, then the created document will contain only the XML prolog.
Note: If the schema or DTD location is incorrect, or the list of possible root elements will be empty
