[Exist-open] Quotation marks in update insert or replace

[<roe...@ed...>]

  Hi everybody,

I?ve found a weird behavior in using xupdate.
I wanted to replace

<node>Text1</node>

with

<node>"Text2"</node>

If you use the command: update value /pathToNode/node with """Text2""" 
it is all fine.
If you use one of the commands: update replace /pathToNode/node with 
<note>""Text2""</note> or update insert <node>""Text2""</node> into 
/pathToNode the Sandbox-Client gives the error: expecting XML end tag, 
found "

Is this a bug or is there a different way to mask quotation marks in 
update replace or update insert.

I am using the stable build "eXist-1.1rc-newcore.jar"

Thanks, Daniel
