I am trying to generate code (with customizations applied) for OTA schema available at [OTA2003B] ( http://www.opentravel.org/Specifications/SchemaIndex.aspx?FolderName=2003B ) using JiBX Code Gen tool.Following is the code I have written to achieve the same.

When I try to generate code from the configured schemas the code gets generated without the binding files and I get the following error:

I can see that the in both the schemas specified the elements referred to in the error shown above, for e.g. InventoryStatusType are available.And due to this the problem is occurring.But I have specified prefer-inline="true" and different packages for each schema code to be generated in my custom1.xml, which means that for both the schemas the fully qualified name of InventoryStatusType(assuming this would be created as an inner class) would be different and this should not create a duplication error like the one I am encountering.
1) What is that is causing the problem and how generate-all="false" is able to avoid this issue?
2) How to resolve the Duplicate Name error without using generate-all="false"?
Note: When using generate-all="false" binding files gets generated but on compilation of bindings I face the following error:

Updates on this after receving Don's reply
After posting the issue I viewed the OTA schemas online ( http://www.opentravel.org/Specifications/SchemaIndex.aspx?FolderName=2003B ) I was trying to generate code from and I found that the one available at the above link and the one I had was different.So I thought the flattened version of schema I had might be causing the issue.So I downloaded the online version of schemas which is properly structured in the sense that it includes the common schemas i.e.
<xs:include schemaLocation="OTA_VehicleCommonTypes.xsd"/>
<xs:include schemaLocation="OTA_SimpleTypes.xsd"/>
<xs:include schemaLocation="OTA_CommonTypes.xsd"/>
<xs:include schemaLocation="OTA_CommonPrefs.xsd"/>
<xs:include schemaLocation="OTA_AirCommonTypes.xsd"/>
Note: I am not using the OTA_AirCommonTypes.xsd in my code as some errors were occuring related to schema elements in this schema definition.
So I thought now the modular generation technique mentioned about (http://jibx.sourceforge.net/fromschema/example-modular.html ) can help. I proceeded with the same and following is the code I have written:
jibx-maven-plugin configuration
<!-- For applying custom_a.xml customization -->

</includeSchemaBindings>
<options>
<i>src/main/java/base-binding.xml</i>
</options>
</configuration>
My Customization XMLs
custom_a.xml
<schema-set prefer-inline="true" package="com.poc.jibx.ota.common"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
type-substitutions="xs:integer xs:int xs:decimal xs:float"
binding-file-name="base-binding.xml">
<schema name="OTA_CommonPrefs.xsd" />
<schema name="OTA_CommonTypes.xsd" />
<schema name="OTA_SimpleTypes.xsd" />
<schema name="OTA_VehicleCommonTypes.xsd">
<complexType name="VehicleProfileRentalPrefType">
<element path="**" name="VendorPref" ignore="true"/>
</complexType>
</schema>
</schema-set>
custom_b.xml
<schema-set prefer-inline="true"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
type-substitutions="xs:integer xs:int xs:decimal xs:float" >
<name-converter strip-prefixes="OTA_"
strip-suffixes="Type AttributeGroup Group Attributes"/>
<schema name="OTA_VehAvailRateRQ.xsd"
includes="OTA_VehAvailRateRQ" binding-file-name="otaVehAvailRateRQ_binding.xml"
package="com.poc.jibx.ota.vehAvailRateRQ" />

includes="OTA_VehAvailRateRS" binding-file-name="otaVehAvailRateRS_binding.xml"
package="com.poc.jibx.ota.vehAvailRateRS" />
</schema-set>
First I applied custom_a.xml which generated the code and ran the jibx:bind goal which compiled the bindings(base-binding.xml) successfully. Then I commented the configuration section for applying custom_a.xml and enabled the configuration section for applying custom_b.xml which generated the code successfully but running the binding compiler produced following errors:

So now what is it that I am missing or going wrong at and how to fix this? Also is the code I have written in line with the best practice JiBX users should follow or there are improvements I can make?
