Where in our spec does this need to go? Since we have voted, I don't feel like we can change anything more than typo's. The only place I can find any mention is at the beginning of Appendix A but we don't actually use this anywhere. I am still uncomfortable with the idea of use it sometimes and don't use it sometimes. If Company-A points to a url .xsd which does not contain this declaration (and their parser is fine) and then sends to Company-B who's parser chokes without this .xsd declaration, then we have a problem. I understand that the schema can be cached locally and modified but that sounds like trouble to me. If two MSHs point to the same url, then that url should work the same in both cases. David.
