How about abbreviating it to "attr" ?

   tal:content="attr/name"

How about "map" or "mapping" instead?

   tal:content="map/foo"


I don't feel strongly either way about these alternative names. I'm just

That would be nice. Perhaps tie this into adapting to IContainer.

Where do views and resources fit into this?

I expect that it will still be possible to specify custom traversal for 
a particular kind of component.
