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">
