The appearance and content of an IS schema depends on whether you generate an IS schema from an XML schema or a DTD. For example, if you create an IS schema from an XML schema, the resulting IS schema displays type definitions, element declarations, and attribute declarations. If you create an IS schema from a DTD, the resulting IS schema displays element type declarations.

When you select an IS schema in Package Navigator view, Designer displays the contents of the IS schema in the editor. The schema editor is divided into two areas: the Schema browser on the left and the Component Details on the right. Above these areas, the editor identifies the target namespace for the IS schema.
