One characteristic I think we want to keep: neither SOAP core nor SOAP encoding should require schema validation to reproduce a useful data model from an incoming message. We should make clear that any defaulting resulting from assessment with a schema is, as Andrew suggests, at a level above that covered by the SOAP recommendation. ------------------------------------------------------------------ Noah Mendelsohn Voice: 1-617-693-4036 IBM Corporation Fax: 1-617-693-8676 One Rogers Street Cambridge, MA 02142 ------------------------------------------------------------------ Marc Hadley <marc.hadley@sun.com> Sent by: xml-dist-app-request@w3.org 02/18/2002 05:59 AM To: Martin Gudgin <marting@develop.com> cc: XML Protocol Discussion <xml-dist-app@w3.org> Subject: Re: SOAP Encoding: Default values I think its trying to say: An omitted accessor is equivalent to an included accessor with an xsi:nil attribute. The interpretation is application dependent. Typical interpretation would be to substitue NULL or some application dependent default value. Marc.
