You are correct, the test is in error. We will be contacting the W3C XML Schema WG about the erroneous test. -- THINGS TO DO IF I BECOME AN EVIL OVERLORD #5 The artifact which is the source of my power will not be kept on the Mountain of Despair beyond the River of Fire guarded by the Dragons of Eternity. It will be in my safe-deposit box. The same applies to the object which is my one weakness. > -----Original Message----- > From: Tom Preston [mailto:tpreston@amadeusboston.com] > Sent: Friday, March 01, 2002 1:48 PM > To: Stanley Guan; xmlschema-dev@w3.org > Subject: RE: nil="true" and xsi:type="xsd:string" > > > Sorry, hit send by mistake:: > > hum...so the page says that it shouldn't be valid, and yet it > passes validation... > > I don't know why it would be wrong: > > spec says: > 2.6.1 xsi:type > The Simple Type Definition (§2.2.1.2) or Complex Type > Definition (§2.2.1.3) used in ·validation· of an element is > usually determined by reference to the appropriate schema > components.
