Hello Andrew,

if my understanding is correct, the result that you expect is incorrect:

<results> {
for $x in ("A String","B String","C String","D String","E String","F String","G String","H String","I String","J String","K String","L String","M String","N String","O String","P String","R String","S String","T String","U String","V String","W String","X String","Y String","Z String")
 order by xs:string($x) return xs:string($x)
}
</results>

I expect the following result:

<results> A String B String C String D String E String F String G String H String I String J String K String L String M String N String O String P String R String S String T String U String V String W String X String Y String Z String
</results>

and not:

<results>A String B String C String D String E String F String G String H String I String J String K String L String M String N String O String P String R String S String T String U String V String W String X String Y String Z String</results>

I miss the leading blank (after <results>) and the cr between } and </results>. 

Regards

Dirk
