Mukul Gandhi resolved XERCESJ-1601.
-----------------------------------
Resolution: Later
there hasn't been a consensus on this issue so far. I might have been right
with my previous comments on this issue. This is a design issue with Xerces-J
IDC framework, and to my opinion modifying parts of IDC implementation logic
which might achieve this functionality is not a trivial and risk free change.
My suggestion is to take this up later, and hence I'm marking the resolution of
this issue as 'Later'.
> Keyref to a key in a different scope

> Key: XERCESJ-1601
> URL: https://issues.apache.org/jira/browse/XERCESJ-1601
> Project: Xerces2-J
> Issue Type: Bug
> Components: XML Schema 1.1 Structures
> Affects Versions: 2.11.0
> Reporter: Octavian Nadolu
> Priority: Minor
> Attachments: keyref1_1.xsd, keyref1_2.xsd, keyref1.xml, keyref2.xml,
> keyref2.xsd
>
>
> If I validate the "instance.xml" with the XML Schema "test.xsd" I get the
> following error:
> cvc-identity-constraint.4.3: Key 'kr' with value 'a2' not found for identity
> constraint of element 'parent'.
> I tested on the xml-schema-1.1-dev branch.
> Xerces discards all the key defined on "child" elements except the ones
> defined on the last "child" element. In the example only the "a1" and "a4"
> values are used when the keyref is checked.
> The schema added below defines a key on the "child" element selecting the
> "element/@id" attribute and a key reference on the "parent" element that
> specifies that "test/@ref" points to "child/element/@id" attributes.
> All the keys defined in the "child" elements should be valid, except the ones
> that are duplicates. There is a discussion about this on the XML Schema Dev
> list:
