| '''Summary'''

|Checks if the specified {{Code|$sequence}} has at least {{Code|$min}} and, optionally, at most {{Code|$max}} items. Equivalent to:

let $count := count($sequence)

return $count >= $min and $count <= $max

| '''Summary'''

|Returns items from {{Code|$sequence}}, starting at position {{Code|$first}} and ending at {{Code|$last}}. Equivalent to:

subsequence($sequence, $first, $last - $first + 1)

</syntaxhighlight>

| '''Summary'''

|Returns nodes in ''distinct document order'': duplicate nodes will be removed, and the remaining nodes will be returned in [https://www.w3.org/TR/xquery-31/#dt-document-order document order]. As results of path expressions are brought distinct document order before they are returned, the function is equivalent to:

$nodes/self::node()

</syntaxhighlight>

| '''Summary'''

|Returns the document nodes of the specified {{Code|$nodes}}. The path expression <code>/abc</code> is internally represented as <code>util:root(.)/abc</code>. Equivalent to:

$nodes ! /
