    • makeRandomId

      INTERNAL: Make a random ID-like string of the given number of characters.

    • normalizeId

      public static String normalizeId(String name)
      INTERNAL: Creates a candidate ID from an input string. The algorithm discards characters above U+00FF, strips accents off remaining characters, then discards everything that doesn't match the LTM NAME production (except leading characters, which turn into underscores). Whitespace is normalized, and turns into a hyphen when internal to the string. Letters are lowercased.
