No. It gives an error..

The problem is that I don't really know how to test if a "metal" slot 
has been "called" or not.

<td tal:condition="here/secondary | nothing">
    <div metal:define-slot="secondary">secondary content</div>
</td>

It is my: tal:condition="here/secondary | nothing", that doesn't do what 
I would like it to.

It really should test false if:

<div metal:fill-slot="secondary">something</div>

hasn't been defined in the zpt using my macro. Or something to that effect.

The only solution that comes to mind right now, would be if I had two 
different macros. One for two columns and one for three columns. But 
that is unelegant and leaves the possibility that the 2 files come out 
of sync. So I really would prefer just one macro.
