My personal take is that namespaces are good for all the reasons that 
namespaces are useful in other programming contexts.  Among these are the 
ability to re-use types defined in separate standard (for some definition of 
standard) type libraries.  But just because your schema uses the 'widget' 
type declared in the 'http://widgetlib.org' namespace shouldn't necessarily 
mean that 'http://widgetlib.org' should appear in your instance documents.
