Ok, thanks.
There are some useful patterns.
It's very unfortunate that this things are not well documented.

I don't (still) know if this will be really useful, but I would like to
have something like:
class MyPage(page.Element):
def __init(self):
self.x = {'y': 1}
self.x = data(self.x)
<p n:render="string" n:data="x.y" /> ==>
<p>1</p>
For the sequence renderer, the solution used by Django is to "push" the
loop variable into the context (used as a stack).
The problem is that in Nevow template we can not name this variable.
This means that one have to do:
<ul n:render="sequence" n:data="list">
<li n:data="@sequence" n:render="string" />
</ul>
