Hi Robby,
You get string since your function basictypes:getPackage() has return
type xs:string
(and according to the XQuery specification any element can be casted to
xs:string by getting it's text value). Try to change:
declare function basictypes:getPackage($*basictype* as element(Product)) as
xs:string
to the:
declare function basictypes:getPackage($*basictype* as element(Product)) as
element(Package)
