isNillable Property
[This feature was only implemented for MSXML 6.0.]
This function retrieves the nillable attribute of the element. A nillable element is valid with no content, even if its content type requires content. For an element to be nillable, its declaration must have the attribute xsd:nillable with a value of true, and its instance element must have the attribute xsi:nil with a value of true. The element must be empty, but it can have attributes declared in its <complexType> declaration.
