Identity-constraint

[Faroukh Fekravar <fekravar@austin.apc.slb.com>]

Folks,

I'm validating my xml instance (generated manually) based on the schema
below by using XSV
and get the 'cvc-identity-constraint.2.3.2' error.
(No key or unique constraint named Item1Key declared, refed by keyref
Item2_KeyRef)
I'm not usre whether I'm missing something here or XSV has some
limitation/bugs.

I would appreciate your help.

Thanks,
Faroukh

XML Instance:
<Project

 <Item1 Item1_2="123">
  <Item1_1>999</Item1_1>
 </Item1>

 <Item2 Item2_2="123">
  <Item2_1>999</Item2_1>
 </Item2>

</Project>

<xsd:element name="Project">
<xsd:complexType>
 <xsd:sequence>
 <xsd:element ref="Item1" minOccurs="0"/>
 <xsd:element ref="Item2" minOccurs="0"/>

  </xsd:key>
