When you add a schema file, the Developer tool imports all .xsd files that are imported by or included in the file you add. The Developer tool validates the files you add against the files that are part of the schema object. The Developer tool does not allow you to add a file if the file conflicts with a file that is part of the schema object.
For example, a schema object contains root schema file "BostonCust.xsd." You want to add root schema file "LACust.xsd" to the schema object. Both schema files have the same target namespace and define an element called "Customer." When you try to add schema file LACust.xsd to the schema object, the Developer tool prompts you to retain the BostonCust.xsd file or overwrite it with the LACust.xsd file.
You can use the
attribute to mark XSD elements as nillable. When you mark an element as nillable, the corresponding element in the XML file permits null values.
You can remove any root-level schema file. If you remove a schema file, the Developer tool changes the element type of elements that were defined by the schema file to xs:string.
