           Summary: [XQuery30] group by variables with associated
                    expressions
           Product: XPath / XQuery / XSLT
           Version: Member-only Editors Drafts
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: normal
          Priority: P2
         Component: XQuery 3.0
        AssignedTo: jonathan.robie@gmail.com

At our Sept. 13 meeting [1] we accepted:

DECISION: Adopt Andrew's proposed ammendment of 'group by' syntax as 
described in 
http://lists.w3.org/Archives/Member/w3c-xsl-query/2011Aug/0035.html


This proposal added a transformation, turning:

group by $g1, $g2 := $expr1, $g3 := $expr2 collation "Spanish"

into:

let $g2 := $expr1
let $g3 := $expr2
group by $g1, $g2, $g3 collation "Spanish"


In our draft spec, I see instead that:

group by $g1 collation "Spanish"

is equivalent to:

group by $g1 := $g1 collation "Spanish"
