> The primer has an example of deriving a complex type, "ConfirmedItems", from an existing complex type, "ipo:Items". > > The base complex type has an element defined locally with a locally defined type. > > The derived type is attempting to restrict the occurance of the base's locally defined element. > > There is a note in the Structures Spec, Schema Component Constraint: Particle Restriction OK (Elt:Elt -- NameAndTypeOK), stating > NOTE: The above constraint on {type definition} <\l > means that in deriving a type by restriction, any contained type definitions must themselves be explicitly derived by restriction from the corresponding type definitions in the base definition. > The not seems to say that the type associated with the elements must also be derived from the base, yet the Primer's example is working with only locally defined types. > > Question1: Is the Primer example in 4.4 a valid representation of a restriction? > Question2: For the purposes of derivation, are two local elements with locally defined types supposed to be treated as identical or should the element be defined globally and then referred to? > > Thanks, > > Dave Brown > * Software Design Engineer/Test > * davebrow@microsoft.com > * (425) 705 - 0804 > >
