def cucumber_features_node
  # XPath is case-sensitive so I'm using the translate function as
  # described in a blog post titled "Performing a Case In-sensitive
  # search in an XML Document" by Harish Ranganathan
  # http://geekswithblogs.net/ranganh/archive/2005/09/12/53520.aspx
  #
  # There may be functions in XPath version 2 that provide a better way
  # to do case-insensitive search but as of this writing REXML only
  # implements XPath 1.0.
  #
  # Because the search is for a specific string, only those characters
  # need translated to lower case.
