XmlSchemaRedefine Class

Allows simple and complex types, groups, and attribute groups from external schema files to be redefined in the current schema. This class provides versioning for the schema elements. Represents the World Wide Web Consortium (W3C) redefine element.

For a list of all members of this type, see XmlSchemaRedefine Members.

Thread Safety

Remarks

This class does the following:

The redefine element requires that the external elements exist in the same target namespace as the redefining schema. Schemas without a namespace can also be redefined using the redefine element, in which case the redefined components become part of the target namespace of the schema.

The definitions within the redefine element itself must use their current definitions as their base type definition. Attribute group definitions and model group definitions must include one and only one reference to themselves. Note that not all the definitions of the redefined schema document must be redefined.

Redefining elements may cause unexpected results, such as ill-formed definitions, on other type definitions that are based on the redefined definitions.

This provides a mechanism for versioning of schema types.
