Summary
In this chapter we introduced the commonly used XML schema structures. We created an XML schema in Oracle JDeveloper Schema Visual Editor. We discussed the various methods by which XML schema components may be added to an XML schema. Subsequently, we registered the XML schema in JDeveloper. Registering a schema associates the schema with a specific file extension. We created an XML document that conformed to the XML schema. In the next chapter we shall validate an XML document with an XML schema.
