Property Value

XmlSchemaDerivationMethod

An XmlSchemaDerivationMethod value representing the different methods for preventing derivation. The default value is XmlSchemaDerivationMethod.None.

Remarks

The block attribute prevents a complexType or element that has the specified type of derivation from being used in place of the inherited complexType or element. This attribute's value can either be a white space separated list of restriction, extension and substitution or the value can contain #all or a list that is a subset of extension, restriction, or substitution.
