    Description

      When I parse the following schema I get a NullPointerException. The open content element from the schema does not have an wildcard set yet. So, Xerces presents correctly the error about the open content but then it gets a NullPointerException.
      I tested on the xml-schema-1.1-dev branch.

      ------------Schema----------------------------
      <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified">
      <xs:defaultOpenContent mode="interleave">
      <xs:any namespace="##targetNamespace"/>
      </xs:defaultOpenContent>
      <xs:complexType name="mainCT">
      <xs:all>
      <xs:element name="elemA" type="mainCT"/>
      </xs:all>
      </xs:complexType>
      <xs:complexType name="bCT">
      <xs:complexContent>
      <xs:extension base="mainCT">
      <xs:openContent mode="interleave">
      </xs:openContent>
      <xs:all>
      <xs:element name="elemB"/>
      </xs:all>
      </xs:extension>
      </xs:complexContent>
      </xs:complexType>
      </xs:schema>
