Prety sure you can avoid the text {} and () and just do
"Id	Name",
for $i in $doc/item return
concat($i/id, "	", $i/name)

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))
