recursion
[ https://issues.apache.org/jira/browse/XERCESJ-1396?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14289046#comment-14289046 ]

-------------------------------------
This issues doesn't seem to be fixed. See http://stackoverflow.com/questions/28092391/enforcing-xsd-key-and-keyref-constraints-is-not-working-well-with-a-recursive-sc for an example.

> Project: Xerces2-J
> Issue Type: Bug
> Components: XML Schema 1.0 Structures
> Affects Versions: 2.9.1
> Environment: Window, with Eclipse and the xerces plug-in is org.apache.xerces_2.9.0.v200805270400

> Hi everyone,
> Is it true that key/keyref does not validate with recursion? I have this question because that when I validate the following xml file, the validation of an element defined with recursion doesn't work. Following is xml and the corresponding xsd file. (I validate xml file with Eclipse and the xerces plug-in is org.apache.xerces_2.9.0.v200805270400). Thanks in advance!
