Conditional Logic . . . what am I missing?

I need to conditionally include an element in a pipeline and was rather 
surprised that my only option is to use <p:choose>.

I would have thought I should be able to use 'use-when' but that seems 
to only take static values (which makes me wonder about what it is for).

So I am having to use this:

    <p:choose>
    <p:when test="$informative-matches = 0">
    <p:insert match="entity/other-searches" position="last-child">
    <p:input port="insertion" select="/entity/music-search"/>
    </p:insert>
    </p:when>
    <p:otherwise>
    <p:identity/>
    </p:otherwise>
    </p:choose>


When all I really want is this:


    <p:insert match="entity/other-searches" position="last-child"
    use-when"$informative-matches = 0">
    <p:input port="insertion" select="/entity/music-search"/>
    </p:insert>

Hopefully, I am overlooking something obvious ;)

Christopher
