Well, that's the core TAL engine, right?

If I have a path:
/x/y/z
...where x and z are callables (and x needs to be called to get somethat that y 
can be obtained from...) then what would the Zope 3 ZPT/TAL look like to replace 
the contents of <i> with the result of calling z?

Well, Florent proposed that, if the above example, you'd write:

<i tal:contents="root/x/y/z"/>

I don't yet know what your opion would be, but at the moment, I'm in favour of 
Florent's

cheers,
