How about
element {} {}
text {}
attribute {} {}
should those be no-ops too?
I don't think so, because
element {} {"not empty"}
would be problematic

Function bodies should be able to be empty too ... its so simple !
declare function notimplementedyet() {};

I am asking why in *XQuery* the expression {} is not equivalent to {()}
It might simply be that no-one suggested it.
Is there a case in *XQuery* where this would be problematic ?
I don't think so.
Probably the least-impact way for the spec to accomplish this would be
to alter the syntax of EnclosedExpr, from
EnclosedExpr ::= "{" Expr "}"
to
EnclosedExpr ::= "{" Expr? "}"
and then say that, if the Expr is omitted, the EnclosedExpr yields the
empty sequence. Note that, in addition to element and attribute content,
this would also take effect when an EnclosedExpr is used as a function
body, which may or may not be something you'd like as well.
