Why does it matter? What do you mean by "where"? I'm doing it wherever I 
want a rendering of an object relative to another object and maybe with 
a title override. This is primarily for creating internal linking around 
a site but I want to re-use it for things like listing on a contents 
view, etc.

Why browser:page? I _only_ want to be able to do:

tal:content="structure obj/@@render"

...and I think I can get away with not having an explicit context. I 
certainly don't need the title override.

I don't need a template here, I already have an set of adapters for my 
objects which do what I want. I just want to be able to use them sanely 
from inside ZPT's, see my other post.

I'd prefer these to be traversable inside a ZPT but not in a URL, but 
I'd put up with them being url traversable if I really must.

Dammit, why can't I just use a simple adapter :-(
