Building blank XML tags with Nokogiri?

I'm trying to build up an XML document using Nokogiri. Everything is pretty standard so far; most of my code just looks something like:

builder = Nokogiri::XML::Builder.new do |xml|
    ...
    xml.Tag1(object.attribute_1)
    xml.Tag2(object.attribute_2)
    xml.Tag3(object.attribute_3)
    xml.Tag4(nil)
  end

builder.to_xml

However, that results in a tag like <Tag4/> instead of <Tag4></Tag4>, which is what my end user has specified that the output needs to be.

How do I tell Nokogiri to put full tags around a nil value?
