Yep.

Either is fine, but I'd recommend the first one. The second syntax is
more useful when you have your own class you want to use.

Yes, that's my understanding. I really like this action mapper, but
it does need some more thought as to exactly the best way to emulate
ReST in web applications, and better integration from the tag
libraries. The Ruby on Rails community has done some great work in
this area I think we can learn from.
