[Bug 56730] New: [Patch] NPE occurs when exporting a xslx as an XML if attached schema contains ref elements

https://issues.apache.org/bugzilla/show_bug.cgi?id=56730

            Bug ID: 56730
           Summary: [Patch] NPE occurs when exporting a xslx as an XML if
                    attached schema contains ref elements
           Product: POI
           Version: 3.11-dev
          Hardware: PC
            Status: NEW
          Severity: normal
          Priority: P2
         Component: XSSF
          Assignee: dev@poi.apache.org
          Reporter: hae@zuehlke.com

A NPE occurs when exporting a xslx as an XML document if the attached schema
contains ref elements. 

Here is an example of a xml schema which POI can't handle beacause of the
xs:element ref attribute

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified">
    <xs:element name="Entry" type="Type_Entry"/>
    <xs:complexType name="Type_Entry">
        <xs:sequence>
             <xs:element ref="REFELEMENT" minOccurs="0"/>
        </xs:sequence>
    </xs:complexType>

    <xs:element name="REFELEMENT" type="xs:double"/>

</xs:schema>

I'm going to provide a patch for this issue.
