Used to ‘include’ another view inside an existing view. The caller needs to pass the context in which the partial will be rendered Render must be called with :partial as well (other options will be supported later). The partial vale should be a relative path to another file view, from the calling view.

16:       def render(xml, options = {})
17:         # First, we need to identify the partial file path, based on the @view_template path.
18:         partial_path = (@view_template.split("/")[0..-2] + options[:partial].split("/")).join("/").gsub(".xml.builder", "") + ".xml.builder"
19:         raise ViewFileNotFound, "No such file #{partial_path}" unless Babylon.views[partial_path] 
20:         eval(Babylon.views[partial_path], binding, partial_path, 1)
21:       end
