[basex-talk] comment()

Hi, I want to write a comment in the xml I produce with my XQuery. I try to use the comment() function, but each time I want to put something inside the () i have a syntax error.

for example : <test> {comment("test"), let $r := random:integer(100) + 1 for $j in (/*)[$r] return ( $r,$j) } </test>

or (who is more what I want to do)

<test> { let $r := random:integer(100) + 1 for $j in (/*)[$r] return (comment("$r"),$j) } </test>

I don't find any example on how to use the comment function. Anyone have example about that use?

Thanks

Marc
