2.6.1 Can an instance of the data model contain documents from the same namespace that have been validated with different schemas? In that case, there may be different types with the same expanded-QName.
That's not allowed. I've reworded the paragraph in question to make that clearer: The data model relies on the fact that an expanded-QName uniquely identifies every named type. Although it is possible for different schemas to define different types with the same expanded-QName, at most one of them can be used in any given validation episode. The data model cannot support environments where different types with the same expanded-QName are available. Please let us know if this resolution is unsatisfactory.
