  SDL (Specification and Description Language) is an ITU standard (Z.100)
  for a formal specification language used in communications and system specification generally.

  This mode handles SDL/PR (Phrase Representation), but does not (yet) deal with SDL 2000.

  Auto-indentation occurs if the following are at the start of a line (ignoring
  leading white space): "block", "channel", "connection", "decision", "generator", "input", "macro", "newtype", "operator", "package", "procedure", "process", "refinement", "service", "start", "state", "substructure", "syntype", "system".

  This also happens if the following appear on their own (i.e. also ignoring
  trailing white space): "signal".
