       Body:
BTW. Marking the value with ident="ref" as optional does not help. I tried all sort of 
syntax, all lead to some NullPointerException when trying to get a name.

Environment: JDK 1.4.2

Description:
java.lang.NullPointerException
at org.jibx.binding.def.PropertyDefinition.getName(PropertyDefinition.java:308)
at org.jibx.binding.def.ValueChild.createBackfillClass (ValueChild.java:185)
at org.jibx.binding.def.ValueChild.genParseIdRef(ValueChild.java:282)
at org.jibx.binding.def.ValueChild.genUnmarshal(ValueChild.java:400)
at org.jibx.binding.def.ValueChild.genContentUnmarshal(ValueChild.java:587)
at org.jibx.binding.def.NestedCollection.genContentUnmarshal(NestedCollection.java:130)
at org.jibx.binding.def.ObjectBinding.genUnmarshalContentCall(ObjectBinding.java:611)
at org.jibx.binding.def.ObjectBinding.genContentUnmarshal(ObjectBinding.java:723)
...
occurs with the following binding excerpt:
<mapping name="form" class="com.livis.xforms.desc.Form">
   <collection name="constraints" field="constraints"/>
   <value name="typeref" field="typeref" usage="optional"/>
   <collection field="constraintrefs">
      <value name="constraint-ref" type="com.livis.xforms.desc.Type" ident="ref"/>
   </collection>
   <structure field="layout" usage="optional"/>
</mapping>
<mapping name="type" class="com.livis.xforms.desc.Type">
   <value name="name" field="name" ident="def" style="attribute"/>
</mapping>
...
This makes it impossible to unmarshall a list of pointers.
