  #  ##   name          -- match by the "name" key
  #  ##                    This resembles the previous 'tag-only' behavior.
  #  ##   elements      -- match by the keys in the path filtered by the path
  #  ##                    parts specified `elements` below
  #  ## By default, 'elements' is used if the 'elements' option is provided,
  #  ## otherwise match by 'name'.
  #  # match = ""
  #
  #  ## For the 'elements' match strategy, at least one path-element name must
  #  ## be supplied containing at least one key to match on. Multiple path
  #  ## elements can be specified in any order. All given keys must be equal
  #  ## for a match.
  #  # elements = ["description", "interface"]
