------------------------------------------

             Summary: Unparse nilled complex element fails. 
                 Key: DAFFODIL-2183
                 URL: https://issues.apache.org/jira/browse/DAFFODIL-2183
             Project: Daffodil
          Issue Type: Bug
          Components: Back End
    Affects Versions: 2.4.0
            Reporter: Michael Beckerle
             Fix For: 2.5.0


This schema uses a nillable complex element.
{code:java}
<xs:element name="input">
     <xs:complexType>
         <xs:sequence dfdl:separator="%NL;" dfdl:separatorPosition="infix">
             <xs:element name="person" maxOccurs="unbounded" dfdl:occursKind="implicit" dfdl:initiator="Person:" nillable="true" dfdl:nilValue="%ES;" dfdl:nilValueDelimiterPolicy="initiator">
                 <xs:complexType>
                     <xs:sequence dfdl:separator="," dfdl:separatorPosition="infix">
                         <xs:element name="name" type="xs:string" />
                         <xs:element name="age" type="xs:string" />
                     </xs:sequence>
                 </xs:complexType>
             </xs:element>
         </xs:sequence>
     </xs:complexType>
 </xs:element>{code}
Parsing this data:

 
{code:java}
Person:John Doe,29
Person:Sally Smith,34
Person:
Person:Bob Jones,51{code}
 

 That produces this infoset when parsing:
{code:java}
<input xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
   <person>
     <name>John Doe</name>
     <age>29</age>
   </person>
   <person>
     <name>Sally Smith</name>
     <age>34</age>
   </person>
   <person xsi:nil="true"></person>
   <person>
     <name>Bob Jones</name>
     <age>51</age>
   </person>
 </input>{code}
Unparsing dies with error:
{code:java}
Unparse Error: Element {}person does not have a value.{code}
