> Key: XERCESJ-1396

> 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

> Reporter: Chu Minh Toan

> 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!
