A more compact alternative:
(
text { "Id	Name" },
for $i in $doc/item return
text { concat($i/id, "	", $i/name) }
)
This relies on your processor's serialization-as-text to insert the line
endings. I'm not totally sure if that's standard, but it seems to work
for me in one case at least. Can anyone comment on how reliable that is?

Hi,
I can't seem to find valid syntax for output of a value before a for
loop. In this example I want to output a header line ($hdr) to the
results.
Thanks for your help,
Gary
let $doc :=
<doc>
<item><id>1</id><name>item 1</name></item>
<item><id>2</id><name>item 2</name></item>
</doc>
let $hdr := concat('Id', codepoints-to-string(9), 'Name',
codepoints-to-string(10))
for $i in $doc/item return
concat($i/id, codepoints-to-string(9), $i/name, codepoints-to-string(10))
