4.8.4 Order By and Return Clauses


"The dynamic semantics ... is not specified formally. The dynamic
semantics is not specified formally ..."
    Again, repetitive.

"Because an OrderByClause does not effect the type"

"in which the OrderByClause is omitted but a gt comparison is applied."
    If the OrderByClause clause really has no effect on the type, why do
    you need to add "but a gt comparison is applied"?
    And applied to what?


"... == [[ LetClause ... LetClause ]]"
    There shouldn't be big brackets around the RHS.

    It's a bit sneaky how you go back to the non-recursive FLWOR syntax
    for this []-form.

"the following rule ... which specify that"

"mapped to Expr"
    Change to "mapped to a sequence of LetClauses".


"using the same static typing rules"
    Same as what?

"Each OrderSpec is normalized the ..."
    s/the/by the/

"auxiliary atomization normalization rule."
    Delete "atomization"? This rule doesn't appear to be doing atomization.

Norm / rule 2
[[ Expr OrderModifier, OrderSpecList ]]_OrderSpecList
    Italicize OrderModifier.

Norm / rule 2
"for $fs:new1 in Expr"
    Append "return".

    Also, Expr should be normalized.

Norm / rule 2
[[ $fs:new1 gt $fs:new2 ]]_Expr
    'gt' always yields boolean, so it appears that
        $fs:new0 : xs:boolean?
    But since $fs:new0 won't appear anywhere else in the FLWORExpr, how
    does that make a difference to its static typing?
