Nested resource routing

I want to be able to nest arbitrarily deep items in a hierarchical format, and route them based on URI
patterns in Spring.  For example, I can have objects nested like:

    /branches/{branch_id}/
    /branches/{branch_id}/leaves/{leaf_id}/
    /branches/{branch_id}/buds/{bud_id}/

However, the branches can alos be nested, like this:

    /branches/{branch_id}/
    /branches/{branch_id}/branches/{branch_id}/leaves/{leaf_id}/
    /branches/{branch_id}//branches/{branch_id}/branches/{branch_id}/buds/{bud_id}/
etc.

I have my Spring application context set up like this to handle the root instances of "branches":

<bean name="root" class="org.restlet.ext.spring.SpringRouter">
    <constructor-arg ref="application" />

    <property name="attachments">
        <map>
            <entry key="/branches/{branch_id}"
                value="com.example.api.resource.BranchResource"/>
            <entry key="/branches/{branch_id}/leaves/{leaf_id}/"
                value="com.example.api.resource.LeafResource"/>
            <entry key="/branches/{branch_id}/buds/{bud_id}/"
                value="com.example.api.resource.budResource"/>
        </map>
    </property>
</bean>

<!--  Spring Application -->
<bean id="application" class="org.restlet.Application">
        <property name="name" value="exampleAPI"></property>
</bean>

I would like to be able to build my URI patterns so that I can handle the cases where the branches are nested.  Is
this even possible?
