XQuery Update

===Example===

The query…

<pre class="brush:xquery">
insert node <b/> into /doc,
for $n in /doc/child::node()
return rename node $n as 'justRenamed'
</pre>

…applied on the document…

<pre class="brush:xml">
<doc> <a/> </doc>
</pre>

…results in the following document:

<pre class="brush:xml">
<doc> <justRenamed/><b/> </doc>
</pre>

Despite explicitly renaming all child nodes of {{Code|<doc/>}}, the former {{Code|<a/>}} element is the only one to be renamed. The {{Code|<b/>}} element is inserted within the same snapshot and is therefore not yet visible to the user.
