I try to add an standard index on an attribute like the following example.
<xs:attribute name = “ID” type = “xs: string” use=“required”>
The file is well formed. As soon as I change the view to schema/wsdl under XML Spy, all above code disapears and there is only the attribute left like following example
<xs:attribute name=“ID” type=“xs:string” use=“required”/>
I have tried with the latest version of XML Spy and the result is the same. What is the problem and how can I resolve it?
