Your rule would accept any string of non-<& characters except the string
']]>'.  The rule in the spec accepts any string of non-<& characters 
except ones *containing* the string ']]>'.

It rejects them both, as intended.

Actually, the rule could have been more simply written

  [^<&]* - (Char*  ']]>'  Char*)
