jaxb - Nillable on @XmlAnyElement -

i made general class plural elements jaxb.

@xmltransient public abstract class plural<s> {      @xmlanyelement(lax = true)     private collection<s> singulars; } 

with following classes,

@xmlrootelement public class item {      //@xmlvalue // problem xsi:nill , ""     @xmlelement(nillable = true)     private string name; }  @xmlrootelement public class items extends plural<item> { } 

when declare name @xmleement(nilalble = true), works fine. @xmlvalue makes problem between xsi:nil , "".

is there way set nillable = true on @xmlanyelement?

update ----------------------------------------------------------

when item#name annotated @xmlelement, following xml marshalls , unmarshalls successfully.

<items xmlns="http://jinahya.googlecode.com/xml/bind/test">     <item id="-4939700912221365683">         <name xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xsi:nil="true"/>     </item>     <item>         <name>name</name>     </item>     <item>         <name xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xsi:nil="true"/>     </item>     <item id="-8544902644460968391">         <name xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xsi:nil="true"/>     </item>     <item id="525642804765733165">         <name xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xsi:nil="true"/>     </item> </items> 

when item#name annotated @xmlvalue, following output xml marshalls , unmarshals failed on equality testing.

<?xml version="1.0" encoding="utf-8" standalone="yes"?> <items xmlns="http://jinahya.googlecode.com/xml/bind/test">     <item id="7812630870400466385">name</item>     <item>name</item>     <item id="-1067677982428177088"/>     <item id="5609376399324841172">name</item>     <item id="-4755856949417090129"/> </items> 

which seems xsi:nil omitted on each item element. item#equals failed on each items. "" without xsi:nill parsed empty element witch each came nulls. @xmlvalue's problem? @blaise doughan learned @xmlanyelement(lax = true) blog entry anyway. thanks.
