Well I think it indicates that strings are a lot easier to structure.
Xml Schema seems to think so too, for example if I want to make my own
datattype for currency that can have a form #,###,###.## or #.###.###,##
I'm basically left restricting xsd:string by a regular expression - and
what fun that is.
