Adding lexically-scoped variables would not make the resulting grammars context-sensitive, since a variable set in a rule would only affect the expansion of that rule and therefore all the ones it invokes, but not any of its siblings or ancestors in the result tree. The "current coordinate system" is already an implicit set of lexically-scoped variables that parameterize every rule; why not add user-specifiable variables of that sort? 
Please help.

I didn't find the right solution from the Internet.
