I have a big schema with multiple levels with the same name. (I didn't write it!)
Here it is:

Note the 3 elements with the name "Layout". I've tried using a xjb file to change the class name of each one, like this:
<bindings xmlns="http://java.sun.com/xml/ns/jaxb" xmlns:xsi="http://www.w3.org/2000/10/XMLSchema-instance" xmlns:xs="http://www.w3.org/2001/XMLSchema" version="2.1">
<bindings schemaLocation="MetrixJDF.xsd" version="1.0">
<globalBindings localScoping="toplevel" />
<schemaBindings xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc">
<package name="com.metrixsoftware.vdp.jdf">
</package>
</schemaBindings>
<bindings node="//xs:element[@name='JDF']">
<bindings node="//xs:attribute[@ref='ssi:WorkStyle']">
<property name="ssiWorkStyle" />
</bindings>
</bindings>
<bindings
node="//xs:element[@name='ResourcePool']/xs:complexType/xs:sequence/xs:element[@name='Layout']/xs:complexType/xs:sequence/xs:element[@name='Layout']/xs:complexType/xs:sequence/xs:element[@name='Layout']">
<class name="Layout3" />
</bindings>
<bindings node="//xs:element[@name='ResourcePool']/xs:complexType/xs:sequence/xs:element[@name='Layout']/xs:complexType/xs:sequence/xs:element[@name='Layout']">
<class name="Layout2" />
</bindings>
<bindings node="//xs:element[@name='ResourcePool']/xs:complexType/xs:sequence/xs:element[@name='Layout']">
<class name="Layout1" />
</bindings>
</bindings>
</bindings>
That doesn't seem to work. I don't get any errors about the xjb file, but I still get these errors when I run xjc:

Please advise.
I did run into an error, but it was not during xjc compilation (using xjc 2.2.8-b130911.1802) but the generated Java code is illegal due to duplicate static class name Layout in ResourcePool. I could not resolve this using external binding either.
The following modification of the XML Schema -- which does not change the XML layout permits the generation of correct Java code:
<xs:element name="ResourcePool">
<xs:complexType>
<xs:sequence>
<xs:element name="Layout" type="jdf:LayoutLev1"/>
<!-- keep the remainder of the element as it is -->
New complex types:
<xs:complexType name="LayoutLev1">
<xs:sequence>
<xs:element name="Layout" type="jdf:LayoutLev2" maxOccurs="unbounded" minOccurs="0"/>
</xs:sequence>
<xs:attribute type="xs:string" name="Class" />
<xs:attribute type="xs:string" name="DescriptiveName" />
<xs:attribute type="xs:string" name="ID" />
<xs:attribute type="xs:string" name="PartIDKeys" />
<xs:attribute type="xs:string" name="Status" />
</xs:complexType>
<xs:complexType name="LayoutLev2">
<xs:sequence>
<xs:element name="Layout">
<!-- keep the rest till the end of complexType -->
