XmlSchemaRedefine Class


Represents the redefine element from XML Schema as specified by the World Wide Web Consortium (W3C). This class can be used to allow simple and complex types, groups and attribute groups from external schema files to be redefined in the current schema. This class can also be used to provide versioning for the schema elements.

Namespace:   System.Xml.Schema
Assembly:  System.Xml (in System.Xml.dll)


public class XmlSchemaRedefine : XmlSchemaExternal


Initializes a new instance of the XmlSchemaRedefine class.


Gets the XmlSchemaObjectTable , for all attributes in the schema, which holds the post-compilation value of the AttributeGroups property.


Gets the XmlSchemaObjectTable, for all groups in the schema, which holds the post-compilation value of the Groups property.


Gets or sets the string id.(Inherited from XmlSchemaExternal.)


Gets or sets the line number in the file to which the schema element refers.(Inherited from XmlSchemaObject.)


Gets or sets the line position in the file to which the schema element refers.(Inherited from XmlSchemaObject.)


Gets or sets the XmlSerializerNamespaces to use with this schema object.(Inherited from XmlSchemaObject.)


Gets or sets the parent of this XmlSchemaObject.(Inherited from XmlSchemaObject.)


Gets or sets the XmlSchema for the referenced schema.(Inherited from XmlSchemaExternal.)


Gets or sets the Uniform Resource Identifier (URI) location for the schema, which tells the schema processor where the schema physically resides.(Inherited from XmlSchemaExternal.)


Gets the XmlSchemaObjectTable, for all simple and complex types in the schema, which holds the post-compilation value of the SchemaTypes property.


Gets or sets the source location for the file that loaded the schema.(Inherited from XmlSchemaObject.)


Gets and sets the qualified attributes, which do not belong to the schema target namespace.(Inherited from XmlSchemaExternal.)


Determines whether the specified object is equal to the current object.(Inherited from Object.)


Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)


Serves as the default hash function. (Inherited from Object.)


Gets the Type of the current instance.(Inherited from Object.)


Creates a shallow copy of the current Object.(Inherited from Object.)


Returns a string that represents the current object.(Inherited from Object.)

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.
