XML DTD Importer
Use the XML DTD Importer to create type trees that describe the format of XML data.
Many of the type trees that are generated by the Importer Wizard can be immediately used for map development. However, depending on the contents of the interface-specific metadata file, it might be necessary for the generated type tree to be modified using the Type Designer.
You cannot simultaneously have a type tree open in the Type Designer while importing a type tree with the same name.
