Disabling Identity Constraint valiation

[Umesh Chandak]

Hi All,
    I want to put error if my xsd contains the element relared to 
identityConstraints like xsd:selector. Does any one  the function to  
get the error messages if the xsd contains the element related to the 
Identity Constraints. I tried the setFeature  with  
fgXercesIdentityConstraintChecking  with value false but it didn't 
complaint about the presence of identity constraints.

Thanks is advance.

Thanks.
Regards,
Umesh
