Supporting dynamic and translated titles in Apache Tiles

I have a Spring MVC project that uses Apache Tiles. I have implemented so that titles can be read from a message source like this:

<tiles-definitions>    
    <definition name="some-definition" extends="public.base">
        <put-attribute name="title" value="some-definition.title" cascade="true" />
    </definition>
</tiles-definitions>

And in my template file (defined by public.base), I do the following:

<title><spring:message text="" code="${title}" /></title>

Now this works great for static translated titles, but I also want to support dynamic titles, e.g. for displaying a company name. I could do it like this:

<tiles-definitions>    
    <definition name="some-definition" extends="public.base">
        <put-attribute name="title" expression="${company.name}" />
    </definition>
</tiles-definitions>

And then simply output the title in my template like this: <c:out value="${title}" />. However, the problem then is that my code breaks because the value of the title attribute is no longer a message key. I want to be able to support the following scenarios:

1. Static titles, e.g. "About Us"


2. Purely dynamic titles, e.g. "${company.name}"


3. Dynamic titles with translated content, e.g. "Welcome to ${company.name}"

Ideally, I could use expression language within my message source, but I could not get that to work. I have experimented quite a bit with various solutions, but I cannot seem to find a decent one. If I could use expression language within my message source, then this would be easy. For instance, would it be possible to do the following somehow?

some-definition.title = Hello there, ${company.name}

And in my template:

<spring:message text="" code="some-definition.title" var="test" />
<c:out value="${test}" />

The above does not work, as it outputs ${company.name} rather than the actual contents of the variable. Is there a way to make something like this work? Or are there any other ways in which I can support the scenarios that I listed above?

I thought about creating a custom JSTL tag where I would parse a string expression in plain Java code (the string that has been translated), but I realized that I would probably have to explicitly specify the root object for the "variable replacement" to work, as documented here. Then it does not seem like such a dynamic solution.

Is there any way in which I can accomplish this task? Any help is much appreciated!
