not finding all bad data elements at once

[Guillaume Deshors]

Hi

I am facing exactly the issue reported by this oxygen user :
http://www.oxygenxml.com/forum/topic2869.html?sid=a4b044cdcc3c06ae07059f924156f6d3
When using several keyrefs causing errors, Xerces reports only the first and
then gives up.

I would really like to have Xerces report all foreign key errors, like I've
seen with the saxon or libXml parsers. Is there a way to do that ?

I've done a few hours of search and I've read that it is a fatal error to
Xerces and that's why it stops. I've tried to set continue-after-fatal-error
to true but it didn't change anything ; anyway I've read that it's not
recommended to set this option in a production environment.

I'm joining a sample XML and XSD files that show my problem. In my example,
each ASSREGARD references a ASSFILDO, I've created two bad ASSREGARD that
reference non-existent ASSFILDO. Then Xerces reports only :
     Description: [Xerces] cvc-identity-constraint.4.3: Key
'FK_ASSFILDOREGARD' with value 'non-existent1' not found for identity
constraint of element 'FeatureCollection'.
     URL: http://www.w3.org/TR/xmlschema-1/#cvc-identity-constraint

Instead of this I would like it to report both errors, on non-existent1 and
non-existent2. Thank you very much for any support !

Regards, Guillaume
