The only types that are usable in all schemas are the *built-in*
types. The built-in types are the ones shown in the nice diagram at:


The allNNI type that you are talking about is defined in the Schema
for Schema; it is not built-in to all schemas. The fact that the
built-in types and the types defined in the Schema for Schema have the
same namespace does not mean that the types in the Schema for Schema
are built-in.

If you want to have the definitions and declarations that are defined
and declared in the Schema for Schama available in your own schema,
you need to import it:

  <xs:import namespace="http://www.w3.org/2001/XMLSchema"
             schemaLocation="http://www.w3.org/2001/XMLSchema.xsd" />
