a.) What do you think is the difference between "target namespace" and "targetNamespace attribute" b.) Once simpleTypes.xsd was included with contactTypes.xsd they became a single logical schema so they shouldn't be treated as different by a schema processor. ________________________________ From: Paul Spencer [mailto:ps@b...] Sent: Tue 7/1/2003 2:39 AM To: Dare Obasanjo Cc: xml-dev@l... Subject: Re: Chameleon schemas <include>ing chameleon schemas Can you quote a section on this? I have looked at the specification quite carefully, and can't see it. I have also been careful to differentiate between "target namespace" (which I have assumed can be inherited) and "targetNamespace attribute" (which I have assumed cannot).
