Would you please try the latest code? The following schema and sample worked fine.
<?xml version="1.0"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema";>
<xs:complexType name="rootType">
<xs:sequence>
<xs:element name="child" maxOccurs="5">
<xs:complexType>
<xs:simpleContent>
<xs:extension base="xs:string">
<xs:attribute name="attr" type="xs:int"/>
</xs:extension>
</xs:simpleContent>
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
<xs:element name="root" type="rootType">
<xs:unique name="uniqueKey">
<xs:selector xpath=".//child"/>
<xs:field xpath="@attr"/>
</xs:unique>
</xs:element>
</xs:schema>

Here is an overview of the issue:
---------------------------------------------------------------------
Key: XERCESC-1237
Summary: xs:unique is used like xs:key
Type: Bug
Status: Unassigned
Priority: Blocker
Project: Xerces-C++
Components:
Validating Parser (Schema) (Xerces 1.5 or up only)
Versions:
2.5.0

Description:
<xs:unique name="uniqueLNodeType">
<xs:selector xpath="scl:LNodeType"/>
<xs:field xpath="@id"/>
<xs:field xpath="@iedType"/>
</xs:unique>
This xs:unique seems to be validated like xs:key.
In my xml-file there is a <LNodeType id="IED_0001/PROT/LPHD1" lnClass="LPHD">
Xerces tells me, there are not enough values specified for <unique>
If I add an iedType like here: <LNodeType id="IED_0001/PROT/LLN0" lnClass="LLN0"
iedType="frranz">
Xerces seems to be satisfied.
But this is not correct: the fields of an unique needn't to be required. They may be
optional and so they may be missing.
