> Same idea as in Tapestry-2541 but in a much lighter way :
> In my case, I use the Layout pattern for rendering my pages, but depending on the situation, sometimes the body of the layout is empty. In that case I would like to display a generic content. So I imagine something like this : 
> <t:if test="hasBody"> 
> Blah blah blah 
> <t:parameter name="else"> 
> <t:body /> 
> </t:parameter> 
> </t:if> 
> But I don't know how to write the test "hasBody".
