[150] FTWords ::= (Literal | VarRef | ContextItemExpr | FunctionCall | ("{" Expr "}")) FTAnyallOption? In any place in the language where a nested expression is expected we use the normal "(" ")" separators. We should change the "{", "}" to "(", ")". 8095 1 holstege 2006-02-01 21:01:43 +0000 At the face to face meeting we agreed that there was a syntactic ambiguity and curlies are used in other places to solve this sort of problem. Further, full compositionality is useful. On the other hand, things could be simplified to be less confusing; consequently the production will be changed to: FTWords ::= (Literal | ("{" Expr "}")) FTAnyallOption? and the examples changed as necessary.
