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>
