The TypeTree setting is the name of the type tree (.mtt) file that contains the type, which describes the data that is represented by the card.

Cards represent a particular data object. Therefore, each input card and each output card is associated with a type in a type tree that describes the content of that data. Therefore, each card includes a type tree and type name as part of its definition. This type tree is the link between the Type Designer and the Map Designer that communicates the structure and properties of the data to the Map Designer.

You can enter the value for the TypeTree setting. You can also select the value for the TypeTree setting through the Project Browser window. Specify either a type tree (.mtt) file or a native XML schema (.xsd) file. To open the Project Browser window, click the button next to TypeTree under the Value column.

If you select a .xsd file, the NativeXMLSchema properties are added to the card. In the Edit Card window, expand NativeXMLSchema to see the added Identifier, GlobalElements, XSITypes, and MixedContent properties, along with their default values, as shown in the following list.
  • Identifier: <Default>
  • GlobalElements: All
  • XSITypes: None
  • MixedContent: False

Change the default values for the properties by running the Native XML Schema Customization wizard.
