No basis except, of course, the name (xs:token) which IMO is very

That's something on which I have tried to insist as much as possible in
my book about WXS (and now in the corresponding section [1] of my book
about RELAX NG): despite its name, xs:token should be used in most of
the cases where people are using xs:string.

Overusing xs:string leads to XML vocabularies which are needlessly
incoherent about how whitespaces are handled and the confusion on the
name "xs:token" (understood by so many people as a single token while
it's only a "tokenized" string) is the main reason why people keep using
xs:string instead of xs:token.
