HTTPHeader name should be xs:string, not xs:QName

I think there is an error in the HTTP Header component section 6.5.4 XML
Representation [1].  The XML representation shows the 'name' attribute as
type xs:QName, but the other sections describe it as type xs:string. I
assume xs:QName is incorrect and have implemented it as a String in Woden.
