How to reference module types in an XML file?

I'm writing an application that uses the RTI Connector for Javascript. I have an XML file that I converted from an IDL by running rtiddsgen.

In my XML file, the types definition looks like this:

<types>

<module name="Example">

...

<struct name= "busB" extensibility= "final" nested="true">

...

<member name="nestedInsideBusB" type="nonBasic" nonBasicTypeName= "Example::BusC"/>

</struct>

<struct name= "busA" extensibility= "final">
...
<member name="nestedInsideBusA" type="nonBasic" nonBasicTypeName= "Example::BusB"/>

</struct>

</module>

</types>

 I'm trying to define a Domain Library and Participant Library for my application to load.

The Domain Library looks like this:

<domain_library name="MyDomainLibrary">

<domain name="MyDomain" domain_id="0">

<register_type name="busA" type_ref="busA" />

<topic name="MyTopic" register_type_ref="busA"/>

</domain>

</domain_library>

 And the Participant Library looks like this:

<domain_participant_library name="MyParticipantLibrary">

<domain_participant name="MySubParticipant" domain_ref="MyDomainLibrary::MyDomain">

<subscriber name="MySubscriber">

<data_reader name="MyReader" topic_ref="MyTopic" />

</subscriber>

</domain_participant>

</domain_participant_library>

My problem is that the type I want to register lives inside the 'Example' module, so the RTI DDS Connector can't find the type:

DDS_XMLHelper_lookupXmlTypeCode:!get XMLTypeCode

DDS_XMLRegisterType_get_type_code:!get XML TypeCode not found

DDS_FactoryXmlPlugin_assertRegisteredType:!get Type Code from XML RegisterType "busA"

DDS_FactoryXmlPlugin_assertTopic:!Assert registered type

I've tried referencing the type like 'Example::busA' in the <register_type> tag, but I get the same error. How do I register and reference a type that's nested in a module?
