Jeff- Sure, because "Ping" is a type, not an element. If you want to use element instead of type, add a Ping element to the schema. BTW the schema uses the obsolete schema namespace: http://www.w3.org/1999/XMLSchema You should use that of the W3C recommendation: http://www.w3.org/2001/XMLSchema Regards, -- James Yegerlehner Omniopera: XML Schema and WSDL Authoring Software http://www.omniopera.com
