Graphical Representation

Summary

The <xs:override> element is functionally the same as the <xs:refine> element which causes the definitions from an external schema to be included and modified.

The <xs:override> construct allows attributeGroups, complexTypes, group & simpleTypes to be modified.

Added in XSD 1.1 (replaces redefine).

Creating

Inline Properties

Properties that apply to a type are shown inline at the bottom of the items container.

Values that are inherited from the base types are shown in brackets, values specifically set against the item are shown without brackets.

If a facet is not valid for a given type (typically because of its data type), then its value is shown in red.

Inline properties can be disabled in the Options.
