<oXygen/> provides a special type of editor for XML Schema schemas. This editor presents the usual text view of an XML document synchronized in real time with a graphical view of the schema components.
The XML Schema editor of <oXygen/> enhances the content completion of the XML editor inside the xs:annotation/xs:appinfo elements of an XML Schema with special support for the elements and attributes from a custom schema(by default ISO Schematron). This content completion enhancement can be configured from the XSD Content Completion preferences page.
