xjc binding customization does not work in jaxb 2.1.3. It works in jaxb 2.0

I developed a binding customization file in jaxb 2.0 in JDK 1.6.0 and it
worked fine.

Now I'm using jaxb 2.1.3 in JDK 1.6.0_13 and it gives me errors: Error xxx
shows up in more than one properties

which is what the binding file is suppose to be handling by renaming them.

What happened between 2.0 and 2.1.3 that I need be aware of and what do I
need to change. I've searched near and far and can't figure it out. Thanks
so much for your help.

I'm using the binding customization file because the schema has a couple
property names that would get a "catch-all" property because the field name
is used by two different parts of a schema. The 2 fields are called
expression and assertion

I get the following errors

parsing a schema... [ERROR] Element "assertion" shows up in more than one
properties. line 649 of

Failed to parse a schema.

my xjc command is : xjc -extension 090403-0_901-Packet-Schema.xsd -b
binding.xjb

my xjb file is:

<jxb:globalBindings>
    <xjc:superClass name="com.pw.ietm.XMLExtract.IetmElement"/>
</jxb:globalBindings>

<jxb:schemaBindings>
     <jxb:package name="com.pw.ietm.XMLExtract"/>
</jxb:schemaBindings>

<jxb:bindings
node="//xs:complexType[@name='expression_comtype']/xs:choice/xs:sequence[position()=1]/xs:element[@name='expression'][position()=1]">
        <jxb:property name="expressionFirst"/>
</jxb:bindings>

<jxb:bindings
node="//xs:complexType[@name='expression_comtype']/xs:choice/xs:sequence[position()=1]/xs:element[@name='expression'][position()=2]">
        <jxb:property name="expressionSecond"/>
</jxb:bindings>

<jxb:bindings
node="//xs:complexType[@name='expression_comtype']/xs:choice/xs:sequence[position()=2]/xs:element[@name='expression']">
        <jxb:property name="expressionAlone"/>
</jxb:bindings>

<jxb:bindings
node="//xs:complexType[@name='loop-step_comtype']/xs:sequence/xs:element[@name='assertion'][position()=1]">
        <jxb:property name="assertionInitial"/>
</jxb:bindings>

<jxb:bindings
node="//xs:complexType[@name='loop-step_comtype']/xs:sequence/xs:element[@name='assertion'][position()=2]">
        <jxb:property name="assertionChanging"/>
</jxb:bindings>

The schema is very large but here are the area where the error is happening
and I'm trying (successfully in 2.0) to rename assertion and expression
comtype :

<xs:complexType name="loop-step_comtype">
<xs:sequence>
<xs:element name="assignment" type="assignment_comtype" minOccurs="0"
maxOccurs="unbounded"/>
<xs:element name="assertion" type="assertion_comtype" minOccurs="0"/>
<xs:element name="expression" type="expression_comtype"/>
<xs:element name="assertion" type="assertion_comtype" minOccurs="0"/>
<xs:element name="step-seq" type="step-seq_comtype"/>
</xs:sequence>
<xs:attributeGroup ref="common_attrgroup"/>
</xs:complexType>


<xs:complexType name="expression_comtype">
<xs:choice>
<xs:sequence>
<xs:element name="expression" type="expression_comtype"/>
<xs:group ref="binop_elemgroup"/>
<xs:element name="expression" type="expression_comtype"/>
</xs:sequence>
<xs:sequence>
<xs:group ref="unop_elemgroup"/>
<xs:element name="expression" type="expression_comtype"/>
</xs:sequence>
<xs:element name="property-libref" type="property-libref_comtype"/>
<xs:group ref="value_elemgroup"/>
</xs:choice>
<xs:attributeGroup ref="common_attrgroup"/>
</xs:complexType>
