ADF: Translated XLIFF Resource Bundle not Selected at Runtime

Question

Issue: When I run my ADF app in a web browser where French is selected as the default language, the labels on the form are still populated with English text from the default resource bundle, even though an XLIFF resource bundle for French exists.
Details: I have created a default XLIFF resource bundle containing the text for all labels on my form in English, called labels.xlf. I have also created two translated XLIFF bundles for French and German and named them labels_fr.xlf and labels_de.xlf, respectively.
On my form, I have used value expressions to retrieve the text for each component's label, like label="#{res.language}. JDeveloper added '<c:set var="res" value="#{adfBundle['oracle.fosxliff.uitest.labels']}"/>' to the top of my page, so I could access the resource bundle text. Identifying the resource bundle in the faces-config.xml file does not work. However, I did define which locales are supported by my application in this config file.
*NOTE:* When I access these sames resource bundles in a managed bean by utilizing the locale of the UIViewRoot, the correct XLIFF file is retrieved and the translated text is correctly assigned to my components on the form.
Is there some other configuration that I am missing? I was expecting XLIFF files to work similarly to properties files, which do work correctly regardless of whether the text is accessed using value expressions or managed beans.

Ok, I've found the answer.
I've added translatable custom properties on the view implemention
and access these in the code...
