Hi thufir,
The specification might be helpful here [1,2], but essentially it is the thing being processed, given as a sort of global scope.
HTH! Best, Bridger

that's interesting. what's item in this example, and how can it be referenced?
thanks,

On top of the query (in the query prolog), you can bind your database to the context. After that, there’ll be no need to bind it to a variable:
declare context item := db:open("com.w3schools.books"); /bookstore

nevermind, it's:
let $db := db:open("com.w3schools.books") return $db/bookstore
I thought it was unusual because of db:open.

these FLWOR .xq files work as is:
let $db := db:open("com.w3schools.books") for $x in $db/bookstore return $x
or
<new_catalog>{ let $db := db:open("com.w3schools.books") for $x in $db/bookstore/book return <new_book>{$x/title,$x/author}</new_book> }</new_catalog>
Probably a silly question, but, rather than, as in the first query, using $x can I not somehow specify just "/"?
thanks,
