Hi all,

There is a canonical way from the XML standards to express that an XML element is null. Rather than reserving a special value for the data within the element, there's a special *attribute* xsi:nil. Schemas can define a corresponding nillable attribute to say it is possible for an element to use the xsi:nil attribute.

Given the problems we've been having with this Jira issue, would using xsi:nil be a good idea? The only disadvantage I can see is that this solution only works when we are serializing and deserializing to and from XML. We would need to solve the problem all over again for other serialization formats.

See http://www.w3.org/TR/xmlschema-0/#Nils and http://docstore.mik.ua/orelly/xml/schema/ch11_03.htm .

Cheers
