That's correct. But that is the same as saying

  If the entry point is "constant" then 2 + 3 is
  not parseable.

For the above I have

   content -> content   '--'  content              [23]
           -> path-expression '--' content         [N]
           -> path-expression '--' path-expression [N]
           -> ....                                 [X] [W] ....
           -> // person -- // evildoer

Please double-check.

Thanks for looking so deeply into the language. It proves that there
is at least one good person out there.
