Mukul Gandhi commented on XERCESJ-1571:
---------------------------------------
again, it seems you might be using Xerces schema 1.1 beta version. When I check
the schema you've posted, for correctness with XSD 1.1 rules from the SVN code
base, the schema is reported as correct.
The following command doesn't give an error,
java jaxp.SourceValidator -a yourschema.xsd -f -xsd11
> Validation for XML Schema 1.1 never fnishes (ends up in infinite loop)

> Key: XERCESJ-1571

> Project: Xerces2-J
> Issue Type: Bug
> Components: XML Schema 1.1 Datatypes
> Affects Versions: 2.11.0
> Reporter: Radu Coravu
> Original Estimate: 2h
> Remaining Estimate: 2h

> If I validate in 1.1 mode a certain XML Schema, the validation never finishes.
> The XML Schema is below:
> ---------------------------------
> <?xml version="1.0"?>
> <schema xmlns="http://www.w3.org/2001/XMLSchema";
> targetNamespace="a"
> xmlns:a="a">
>
> <!--
> Test Case Type: Valid test
> Description : Tests openContent in complexType derived by restriction
> -->
> <defaultOpenContent mode="suffix">
> <any processContents="lax"/>
> </defaultOpenContent>
> <!-- it looks like right now the restriction doesn't have base openContent
> wildcard but will now have the defaultOC WC -->
> <complexType name="c">
> <openContent >
> <any processContents="lax"/>
> </openContent>
> <all>
> <element name="x" type="integer"/>
> <element name="y" type="integer"/>
> </all>

> <element name="root">
> <complexType>
> <sequence>
> <element name="p" type="a:d"/> <!-- tests openContent -->
> </sequence>
> </complexType>
> </element>
> </schema>

> In the method:
