Description

When validating with XML Schema 1.1 support the following schema:

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified">
<xs:include schemaLocation="testSimple.xsd"/>
<xs:override schemaLocation=""/>
</xs:schema>

which references a very simple schema "testSimple.xsd":

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified"> </xs:schema>

I obtain a stack overflow:
