I forgot to cc xml-dev, to make sure it gets to you (since I've been having some
problems with my web-based mail i will send this there now)
the following fragment
<xs:element name="root" type="one:blah">
<xs:unique name="element1">
<xs:selector xpath="one:element"></xs:selector>
<xs:field xpath="@name"></xs:field>
</xs:unique>
</xs:element>
<xs:complexType name="blah">
<xs:sequence>
<xs:element name="element" minOccurs="0" maxOccurs="unbounded">
<xs:complexType>
<xs:attribute name="name" type="xs:string"/>
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
without a specific type for the name attribute does the uniqueness constraint.
