[xml] IDC bug?

[Frans Englich <frans englich telia com>]

Either I'm not using IDCs correctly(which may very well be the case), or 
there's a bug in xmllint. Consider this schema:

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"; 
elementFormDefault="qualified">
    <xs:element name="test-group">
        <xs:complexType>
            <xs:sequence>
                <xs:element name="test-case" minOccurs="0" 
maxOccurs="unbounded">
                    <xs:unique name="idc1">
                        <xs:selector xpath="."/>
                        <xs:field xpath="@name"/>
                    </xs:unique>
                </xs:element>
                <xs:element ref="test-group" minOccurs="0" 
maxOccurs="unbounded" />
            </xs:sequence>
            <xs:attribute name="name" type="xs:string" use="required" />
        </xs:complexType>
        <xs:unique name="idc2">
            <xs:selector xpath="."/>
            <xs:field xpath="@name"/>
        </xs:unique>
    </xs:element>
</xs:schema>


The following two documents validates.


<test-group name="group1">
        <test-group name="group1"/>
</test-group>

<test-group name="group1">
        <test-case name="test-case1"/>
        <test-case name="test-case1"/>
</test-group>


But as I see it, they shouldn't. Or should they?

This was produced with libxml2 version 20623.


Cheers,
