WS DevCon: Don Box: What?s in a Name: Types and semantics in a web service universe

Brian has a good account of this talk, so won?t repeat it.

 

I find it hard to crystallize key messages of this talk. Don seemed to spend most of his slot making an elaborated preamble and we out of time before delivering the key message.

I think he wanted to explain how to achieve compatibility of types with XML Schema and  WSDL. XML Schema allows in fact substitutions of one type with another ?compatible? type using substitutionGroup attribute. How to use it with WSDL isn?t clear to me.
