-##### ActiveModel::Serializers::Xml
-
-To use the `ActiveModel::Serializers::Xml` you only need to change from
-`ActiveModel::Serialization` to `ActiveModel::Serializers::Xml`.
-
-```ruby
-class Person
-  include ActiveModel::Serializers::Xml
-
-  attr_accessor :name
-
-  def attributes
-    {'name' => nil}
-  end
-end
-```
-
-With the `to_xml` you have an XML representing the model.
-
-```ruby
-person = Person.new
-person.to_xml # => "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<person>\n  <name nil=\"true\"/>\n</person>\n"
-person.name = "Bob"
-person.to_xml # => "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<person>\n  <name>Bob</name>\n</person>\n"
-```
-
-From an XML string you define the attributes of the model.
-You need to have the `attributes=` method defined on your class:
-
-```ruby
-class Person
-  include ActiveModel::Serializers::Xml
-
-  attr_accessor :name
-
-  def attributes=(hash)
-    hash.each do |key, value|
-      send("#{key}=", value)
-    end
-  end
-
-  def attributes
-    {'name' => nil}
-  end
-end
-```
-
-Now it is possible to create an instance of person and set the attributes using `from_xml`.
-
-```ruby
-xml = { name: 'Bob' }.to_xml
-person = Person.new
-person.from_xml(xml) # => #<Person:0x00000100c773f0 @name="Bob">
-person.name          # => "Bob"
