  <!-- 
    Some environments require a WSDL/XSD which explicitly defines all possible types. 
    The UA WSDL/XSD can be modified to support these environments by replacing the 
    definitions of the ExtensionObjectBody and VariantValue complex types with the 
    definitions in the comments shown here. Developers would then define subtypes
    of the ExtensionObjectBody type which explicitly declare a choice between all of the
    complex types used by the system. The ExampleExtensionObjectBody subtype is provides
    a template based on a few common UA-defined complex types.

    Some WSDL/XML compilers have issues with the xs:choice construct. For that reason
    the default declaration of a Variant uses xs:any construct. The schema acutually 
    defined by the specification is provided by the Matrix and VariantValue complex types
    shown in comments below. Application developers can replace the VariantValue declaration
    with the specific declaration if they have a development environment that can handle
