[jira] [Created] (XERCESJ-1507) Identity constraint does not work
if field refers to attribute defined as simple type of list
Identity constraint does not work if field refers to attribute defined as simple type of list
---------------------------------------------------------------------------------------------
Key: XERCESJ-1507
URL: https://issues.apache.org/jira/browse/XERCESJ-1507
Project: Xerces2-J
Issue Type: Bug
Components: SAX
Affects Versions: 2.11.0
Environment: Windows, Java 1.6
Reporter: Damir Sulomar
When a keyref field element refers to attribute defined as simple type of list the identity constraint does not work. Schema and data below.
<?xml version="1.0" encoding="utf-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" >
<xs:element name="Data">
<xs:complexType>
<xs:all>
<xs:element name="Data1">
<xs:complexType>
<xs:attribute name="keydata" type="xs:string" use="required"/>
</xs:complexType>
</xs:element>
<xs:element name="Data2">
<xs:complexType>
<xs:attribute name="keyref" type="keyreftypes" use="required"/>
</xs:complexType>
</xs:element>
</xs:all>
</xs:complexType>
<xs:key name="Keys">
<xs:selector xpath=".//Data1"/>
<xs:field xpath="@keydata"/>
</xs:key>
<xs:keyref name="KeyRefs" refer="Keys">
<xs:selector xpath=".//Data2"/>
<xs:field xpath="@keyref"/>
</xs:keyref>
</xs:element>
<xs:simpleType name="keyreftypes">

</xs:simpleType>

[jira] [Commented] (XERCESJ-1507) Identity constraint does not work
if field refers to attribute defined as simple type of list
Posted by "Mukul Gandhi (JIRA)" <xe...@xml.apache.org>.
[ https://issues.apache.org/jira/browse/XERCESJ-1507?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13029979#comment-13029979 ]
Mukul Gandhi commented on XERCESJ-1507:
---------------------------------------
I think that "keyref" and "keydata" attributes in your example should have compatible data types for the purpose of equality test (if you need these for xs:keyref component). In your case, one is xs:string while the other is list of strings (i.e xs:string+), which to my opinion are incomparable for the purpose of xs:keyref component.
I seem to observe that, identity constraints involving simpleType->list work correctly with Xerces-J, provided the schema types I mentioned as above are comparable. If you make "keydata" attribute in your example as a list type (for e.g "keyreftypes" from your example), I seem to find that your example works fine with Xerces-J.
Therefore it seems to me, that this may not be a valid bug report.

[jira] [Resolved] (XERCESJ-1507) Identity constraint does not work
if field refers to attribute defined as simple type of list

Michael Glavassevich resolved XERCESJ-1507.
-------------------------------------------
Resolution: Invalid
I agree with Mukul's assessment and also doubled checked with a member of the XML Schema working group. Atomic types and list types are not comparable in XML Schema 1.0.
