They should be amalgamated. In the version of the note in 3.11.1.1 there is a typo: In some existing implementations that support updates via proprietary extensions, if the MapValueExpr evaluates to a map or array, the associated value is a new ^ or array with the same values. At [^] insert "map". 121608 1 mike 2015-07-05 20:38:37 +0000 In the same section 3.11.2.1 this is a very confused sentence. The members of a SquareArrayConstructor can be any value, separated by commas. An array has members, a SquareArrayConstructor does not. And the things in a SquareArrayConstructor are not values, they are expressions (ExprSingle). 122000 2 jonathan.robie 2015-07-13 21:28:14 +0000 (In reply to Michael Kay from comment #0) > In section 3.11.2.1 the sentence > > XPath 3.1 has no operators that can distinguish a map or array from another > map or array with the same values. > > is repeated in two separate Notes.

And the things in a > SquareArrayConstructor are not values, they are expressions (ExprSingle). I changed this to: A SquareArrayConstructor consists of a comma-delimited set of argument expressions. It returns an array in which each member contains the value of the corresponding argument expression.
