The use of the curly braces in the grammar of FTWord (production 
150) is not symmetrical with the use of curly braces in the rest
of the XQuery language.



[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 "(", ")".
