## Methods

### <a id="VM_Managed_DAFUL_AttributeDFGOption_GetSchema"></a> GetSchema()

This method is reserved and should not be used. When implementing the IXmlSerializable interface, you should return null (Nothing in Visual Basic) from this method, and instead, if specifying a custom schema is required, apply the  to the class.
