I think it's a Xerces bug - you only define the identity constraint
once, so it's clear where it applies.

One thing about your schema:

>             <element name="Scalar" type="spe:TScalar">
>                 <unique name="NameScalar">
>                     <selector xpath="Attribute"/>
>                     <field xpath="@name"/>
>                 </unique>
>             </element>

The NameScalar unique identity constraint looks a bit strange - Scalar
elements don't have element children named 'Attribute' according to
the rest of the schema. I'm not sure whether that was just a test
example or something, but thought I should bring it to your attention.

Cheers,

Jeni
