'xs:token' is, as someone else (Eric?) recently observed, badly named -- it should be 'xs:tokenizedString' -- it's just 'xs:string' with whitespace='collapse' The _fourth_ <any> element is invalid, however, for the reason you cite. > > I may also still have missed something in the rec and my example may be > > invalid, but the point would remain that if you take 4 W3C XML Schema > > processors on a simple test case, you have very often 4 different answers. > > Two of the products Eric are using are betas (MSXML and Xerces) and > the XML Spy is not the most recent (I don't know if it fixes the > problem, and I don't know if the Turbo XML is the most recent.)

I agree with Rick here -- the REC is not quite 6 months old, there are at least half-a-dozen implementations out there, and they're all upgrading rapidly. I would note that whitespace processing is a long-standing source of corner cases: XML 1.0 processors don't all get it right to this day, and there were several errata in this area. ht -- Henry S.
