It's a complex type rather than a simple type. It validates the same content as xs:string, but it can be extended and restricted (and unioned and listed...) in different ways from xs:string. It's likely to behave differently when you do Java data binding, and it's certainly different when you do type-aware XQuery and XSLT. It does raise the question of why simple types are something radically different from complex types, rather than simply a special case of a complex type that happens to define no children and no attributes.
