jsf 2.0 - Pass an outcome as string into a composite component

I'm creating a simple composite component with jsf2, and i'm stucked because of a stupid problem.

I don't know how to send to the composite an outcome as parameter, which will be used as action on a commandLink.

Exemple : 

<!-- Usage -->
<my:comp myAction="myOutcome" />

<!-- Component -->
<composite:interface>
    <composite:attribute name="myAction" required="true" />
</composite:interface>

<composite:implementation>
    <h:form>
        <h:commandLink action="#{cc.attrs.myAction}" value="Go" />
    </h:form>
</composite:implementation>

<!-- Expected result -->
<h:form><h:commandLink action="myOutcome" value="Go" /></h:form>

I have read this topic, but without success.

The only solution i've found is to use a managed-bean as redirector : 

<h:commandLink action="#{redirectorBean.go(cc.attrs.myMaction)}" value="Go" />.

Someone could help me to achieve this with a better (simpler) solution ?

Thank you

The attribute name must be action and you need to specify the composite attribute's targets attribute which refers the relative commandlink client ID.

Usage:

<my:comp action="myOutcome" />

Composite component:

<composite:interface>
    <composite:attribute name="action" targets="form:go" required="true" />
</composite:interface>

<composite:implementation>
    <h:form id="form">
        <h:commandLink id="go" value="Go" />
    </h:form>
</composite:implementation>
