There is no rule that states that xsi:type should only describe
simpleTypes. Your post is basically stating 

	I'm having a hard time envisioning a scenario where having 
      XML schema type information for an instance document would

Which just means that the kind of problems you have to solve are
different from those that those of us that are interested in strongly
typed data have to solve.
