It might be a bit confusing in case of customizing built-in XML Schema
types because there are two new features used at the same time:

(1) By default the C++ mapping for XML Schema built-in types is
    placed into each generated header file. But you can instruct
    the XSD compiler to generate this mapping into a separate
    file and then include that file in other generated files.
    You generate such a header with the --generate-xml-schema
    option and include it in other generated headers with
    --extern-xml-schema (for more information on the semantics
    of these options see the XSD Compiler Command Line Manual[1]).

(2) You can customize the XML Schema built-in types with the
    --custom-type option as described in the C++/Tree Mapping
    Customization Guide[2]. However, you can only do this when
    you are generating the XML Schema built-in types mapping
    into a separate file as described in (1). 

So if you want to customize a built-in type in your application you
have to make two changes (1 and 2 above) at the same time.
