You also need to apply a different writer when an xsi:type is provided.
With xsi:type, you are permitted to specify any type which inherits from
the base type.  There can be many of those... for instance, all types
extend xsd:anyType.  The processing of each element would need an
additional big switch for the case that xsi:type is being used.
See the problem with performance and memory use?

xsi:type frustrates translators implemented as a functional compiler.
It is simple to implement in a message interpreter written in a real
OO language.
