I still think an 'except' operator (see
https://github.com/invisibleXML/ixml/issues/249 for a lot of discussion)
is still worth considering and has plenty of use cases - many EBNF
grammars use similar.
For example in the XPath grammar we can very conveniently use:
|FunctionName: QName ¬ ("if";"element"....).|
It's not the same as a 'not' operator
