Consider the following scenario. You specify the value of the xsi:type attribute of a union element. Then, you use XQuery to query against the XML data that contains the union element. In this scenario, the query returns the incorrect type for the union element.
This problem occurs because the value of the xsi:type attribute of the union element will be the primitive base type of the value. During XML serialization, the primitive base type that is actually set for the value of the xsi:type attribute is returned.
