As I understand, it is a preferred practice to use URL instead of URN for the targetNamespace attribute value of an XML schema. And the primary reason is that one could use the XSD namespace URL to document the use of an XML schema.
See: http://xsd.stylusstudio.com/2009Sep/post01000.htm However, I wonder if this practice should also be applied to the targetNamespace attribute value of a WSDL document. I don't see as strong a reason to do so as for XML schema. What do you think? Thanks, Scott Tsao The Boeing Company
