Does it work if you use <ad:ReturnValue>$1</ad:ReturnValue> ?

I have something like this in attribute-resolver:
        <ad:ValueMap>
            <ad:ReturnValue>some_string_to_add_before_val:$1</ad:ReturnValue>
            <ad:SourceValue>(.+)</ad:SourceValue>
        </ad:ValueMap>

and it works for me.
