nilAttribute

Configuration that specifies whether an attribute is used to indicate a null value (such as the xsi:nil attribute from xml schema). The value is a pair of the QName of the attribute and the string to indicate that the value is in fact null.

For serializing this property means that (for tags only ) the tag will be written with empty content and the given attribute. For attributes or a null value the element is not written at all.

Note that the isAlwaysDecodeXsiNil attribute will allow decoding to decode the xsi:nil attribute even if no nil attribute is configured.
