You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: attribute.rb
    path of file: ./repos/powerstation/powerstation/lib/compiled-jruby/lib/ruby/stdlib/rexml
    
    the code of the file until where you have to start completion: require "rexml/namespace"
require 'rexml/text'

module REXML
  # Defines an Element Attribute; IE, a attribute=value pair, as in:
  # <element attribute="value"/>.  Attributes can be in their own
  # namespaces.  
    
    def initialize( first, second=nil, parent=nil )
      @normalized = @unnormalized = @element = nil
      if first.kind_of? Attribute
        self.name = first.expanded_name
        @unnormalized = first.value
        if second.kind_of? Element
          @element = second
        else
          @element = first.element
        end
