Working with the schema source of a data model
In the data model editor, you can click the Schema Source tab to switch to the XML schema source of the data model.
Because Talend MDM uses XSD as the language to support data modeling and to make it easier to import existing XML schemas, you can use any of the XSD capabilities in any of the XML schema views.
You can edit the XML schema source directly to customize the business entities and attributes as required, and take advantage of such features as code-assist and syntax highlighting.
