David Orchard's take: http://www.pacificspirit.com/blog/2004/01/12/web_services_or_distributed_objects He talks about "must ignore" and "touchless extensibility". He talks about Schema <xs:any>, but that it must be put into the schemas rather than default to must ignore. Note that SOAP has "mustUnderstand" that can be powerful, especially if the default is must ignore. Dave concludes by saying "I do think that the community should provide an easier model for creating and validating extensible xml languages." I'm not sure what "constraints" we could provide in WSA to address this concerns. I always liked this 2002 article http://www.xml.com/pub/a/2002/03/20/endpoints.html which states "Unfortunately, many XML-based applications are actually loosely typed but tightly coupled, which is the worst combination. This is one of the reasons adoption of XSD is a good idea." Paul
