You're quite right that there's no way to look up a particular nested element by name.
Nested elements don't have to have a unique name, so there was really no way to easily
do it in any case - other than returning a collection.
Also, typically there's no need: A Model usually builds a response in reaction to a
request, it seldom has a need to fish through the response directly for nested
elements. Aleks, maybe you can tell us a bit more about the context of the issue so we
can help - there may be a different way to get where you're going.
I have no particular objection to adding a method to retrieve nested elements (or a
collection of them) by name, but I'm having a hard time imagining when I'd want to use
it :-)
