Re: First bug in spec...

Alas! I had completely failed to see in the past that there is a class LC! 
And the ixml rule for a class is:


        -class: code.
         @code: capital, letter?.
      -capital: ["A"-"Z"].
       -letter: ["a"-"z"].


Thus, our first bug...


Easiest fix is


    -letter: [a-zA-Z].
