An <any/> tag is a set of name/value pairs. The only valid mapping that can be determined at design time for <any/> is another <any/> or anyType that has the same maxOccurs value.
Individually, the values contained in an instance of a DataObject for any are basic complex types that follow all the rules of complex type mapping. Some of these complex types may be wrapped simple types, so these will follow the rules of simple type mapping.
