Remarks

You can examine and set this property in the Visual Studio Properties window when you select a Record (including a root Record node) or Field Element node in BizTalk Editor.

This property represents a standard XSD construct.

In instance messages, the use of the nil attribute must include the namespace prefix for the XML Schema namespace for instances, https://www.w3.org/2001/XMLSchema-instance.xsd, which is "xsi" by convention. An element in an instance message that includes the attribute setting xsi:nil="true" may not have any element content but it may still have attributes.
