      "Ruby" are short runs of text alongside the base text, typically
      used in East Asian documents to indicate pronunciation or to
      provide a short annotation. The full specification for Ruby is here:
      
        http://www.w3.org/TR/2001/REC-ruby-20010531/
      
      This module defines "Ruby " or "complex Ruby" as described
      in the specification:
      
        http://www.w3.org/TR/2001/REC-ruby-20010531/#complex
    
      Simple or Basic Ruby are defined in a separate module.
      
      This module declares the elements and their attributes used to
      support complex ruby annotation markup. Elements defined here
            * ruby, rbc, rtc, rb, rt, rp
      
      This module expects the document model to define the
      following content models
        + InlNoRuby.mix
