--- Comment #16 from Christian Gruen <christian.gruen@gmail.com> ---
I just reopened the issue, as there is already a TransformExpr in XQuery 3.0
Update:

[206] TransformExpr ::= "copy" "$" VarName ":=" ExprSingle (","
      "$" VarName ":=" ExprSingle)* "modify" ExprSingle "return" ExprSingle

We could rename the new expression to ModifyExpr or something similar.

Next, I still wonder why/if we really need three tokens..

  "transform" "with" "{"

..or if we could get rid of "with" or "{"? In my initial proposal, I suggested
to move the expression within AndExpr and ComparisonExpr; would this help?
