      "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 Basic" or "simple Ruby" as described
      in the specification:
      
        http://www.w3.org/TR/ruby/#simple-ruby1
        
      This module declares the elements and their attributes used to
      support simple ruby annotation markup. Elements defined here are
          * ruby, rb, rt, rp
      Ruby Basic does not use the rbc or rtc elements.
      The content of the ruby element for Ruby Basic
      uses the rp element for fallback purposes.
