You didn't say how this is arranged in your schema (as xs:any,
polymorphism, etc). If it's done with wildcards (xs:any), see the
`wildcard` example for how handle this. If it's via polymorphism,
then see the `polymorphism` example. There is also an ad hoc
approach that can be used with either as shown in the `messaging`
example.
