Element '{http://www...}ResponseDetails': The type definition is abstract

Got following 开发者_开发技巧error when validating xml response against the xsd. What does this excactly means?

It means that either the element, or the type assigned to it, has the abstract="true" attribute set on it. This means that you cannot use it in the XML document.

You may be able to use xsi:type to override the type of the element.
