'xs:token' is, as someone else (Eric?) recently observed, badly named
-- it should be 'xs:tokenizedString' -- it's just 'xs:string' with
The _fourth_ <any> element is invalid, however, for the reason you cite.

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.
