XML Schema 1.1 Support

Oxygen enhances its XML Schema features to include XSD 1.1 capabilities. The full 1.1 specification is implemented so you can edit and validate 1.1 schemas in both the Text and Design modes.

Oxygen offers full support for XML Schema 1.1, including:

  • XML Documents validation and content completion assistance, based on XML Schema 1.1
  • XML Schema 1.1 validation and content completion assistance
  • Editing XML Schema 1.1 files in the schema Design mode
  • The Flatten Schema action
  • Resource Hierarchy/Dependencies view and refactoring actions
  • Main Files
  • Generating documentation for XML Schema 1.1
  • Support for generating XML instances, based on XML Schema

XML Schema 1.1 is a superset of XML Schema 1.0 and offers numerous other powerful capabilities.


Significant additional features in XSD 1.1 include assertions, conditional type assignment, and open content. To see the complete list of changes since version 1.0, go to http://www.w3.org/TR/xmlschema11-1/#ch_specs.

XML Schema 1.1 is intended to be mostly compatible with XML Schema 1.0 and to have approximately the same scope. It also addresses bug fixes and brings improvements that are consistent with the constraints on scope and compatibility.
