Adding an enumeration Constraint for a simpleType Component in an XML Schema File

See Also

When you define a simpleType schema component, you can restrict the values of the component to specific values in the instance document by using an enumeration constraint.

To add an enumeration constraint:

  1. In the IDE, open the schema file where you want to add the enumeration component.
  2. In the Schema view, right-click the node of the simpleType schema component where you want to add the enumeration component and choose Add > Enumeration from the pop-up menu.
    The IDE adds an enumeration node. The label of this node shows that no value has been defined for the enumeration: ""(Enumeration).
  3. Select the new ""(Enumeration) node, right-click and choose Properties from the pop-up menu.
  4. In the Properties dialog box, type a value in the text box for the Value property.
    You can also click the ellipsis (...) button to use enter or change the value.
  5. Click OK.
    The ""(Enumeration) node has been changed to show the value you entered: "value-entered"(Enumeration)
