你如何在XQuery 3.0中返回多个值？

I've tried a few things:

我尝试了一些事情：

for $name in ('Hanz', 'Heinz', 'Hans', 'Huns', 'Hund')
where $name contains text 'Hans' using fuzzy
return $name | $name
(: returns error: Stopped at line 3, column 20: [XPTY0004] 
Union expression: node() expected, xs:string found. :)


for $name in ('Hanz', 'Heinz', 'Hans', 'Huns', 'Hund')
where $name contains text 'Hans' using fuzzy
return $name and $name
(: returns true :)

for $name in ('Hanz', 'Heinz', 'Hans', 'Huns', 'Hund')
where $name contains text 'Hans' using fuzzy
return $name, $name
(: returns error: Stopped at line 3, column 19: [XPST0008] 
Undefined variable $name. :)
for $nam
