Does from\_xml work with nested associations? Meaning can I pass in a  
person object with associated addresses and have it correctly  
rehydrate the ActiveRecord model for person?

Hi,

a quick look at the documented source:

(see  
[ActiveRecord::Serialization](http://api.rubyonrails.org/classes/ActiveRecord/Serialization.html#M001138))

128: def from\_xml(xml)  
129: self.attributes = Hash.from\_xml(xml).values.first  
130: self  
131: end

So it just sets attributes and does nothing with associations, it  
would appear.
