| {{Code|util:map-values}}
| '''Summary'''
|Checks if the specified {{Code|$sequence}} has at least {{Code|$min}} and, optionally, at most {{Code|$max}} items. Equivalent to:
<syntaxhighlight pre lang="'xquery"'>
let $count := count($sequence)
return $count >= $min and $count <= $max
</syntaxhighlightpre>
|- valign="top"
| '''Examples'''
| '''Summary'''
|Returns items from {{Code|$sequence}}, starting at position {{Code|$first}} and ending at {{Code|$last}}. Equivalent to:
<syntaxhighlight pre lang="'xquery"'>
subsequence($sequence, $first, $last - $first + 1)
</syntaxhighlightpre>

| '''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 into distinct document order before they are returned, the function is equivalent to:<syntaxhighlight pre lang="'xquery"'>
$nodes/self::node()
</syntaxhighlightpre>

| '''Summary'''
|Returns the document nodes of the specified {{Code|$nodes}}. The path expression <code>/abc</code> is internally represented as <code>util:root(.)/abc</code>. Equivalent to:
<syntaxhighlight pre lang="'xquery"'>util:ddo($nodes x ! /)</syntaxhighlightpre>

* Remove all namespaces from an element and its descendants:
<syntaxhighlight pre lang="'xquery"'>
util:strip-namespaces(<xml xmlns='uri' xmlns:prefix='uri2' prefix:name='value'><prefix:child/></xml>)
(: yields :)
<xml name='value'><child/></xml>
</syntaxhighlightpre>
* Remove all default namespaces:
<syntaxhighlight pre lang="'xquery"'>
<xml xmlns='uri1'><child xmlns='uri2'/></xml>
=> util:strip-namespaces('')
</syntaxhighlightpre>
