Hi Adam, Adam Retter <Adam.Retter@landmarkinfo.co.uk> writes: > <xs:complexType name="Classifier"> > <xs:sequence/> > <xs:attribute name="pid" type="xs:string" use="required"/> > </xs:complexType> Having an empty sequence like this is valid and is equivalent to not having one at all. If the schema is auto-generated then it is easy to see why there are empty sequence elements. The tool probably just adds the sequence element (e.g., in DOM) and then iterates over elements and adds them under it. In cases where there are no elements you end up with an empty sequence. Someone may also want to do this in a manually-created schema to highlight the fact that this is a complex type with empty content (and not just a mistake).
