Andrew Welch scripsit: > The extreme flip side is an XSD where everything is optional, which > doesn't do anyone any good, Actually, it can. $EMPLOYER provides an interface of the form "Tell me all you know about a real-world entity with the following properties". Both request and reply use the same all-is-optional schema. Obviously, if the request contains only obscure properties, you may get back no results; likewise, it's possible that the properties you supply are all we know, so we echo them back to you. But without the schema, there would be no agreement about which properties are available, or how they are denoted. -- What asininity could I have uttered John Cowan <cowan@ccil.org> that they applaud me thus? http://www.ccil.org/~cowan --Phocion, Greek orator
