Guten Tag, die Herren!

I have a question about how I can insert, replace a node with a DOM node, instead of the text of that node.

Right now when I 

1) execute from the basex shell this command:

xquery replace value of node /text//sent[@id=15] with <sent id=15><clause><word/><word/><word/></clause></sent>

2) and then look at that node again with 

i see that the dom has been converted into a text node of &lt;sent id=15&gt;&lt;clause&gt;&lt;word/&gt;&lt;word/&gt;&lt;word/&gt;&lt;/clause&gt;&lt;/sent&gt;

How can I replace with true DOM and not have it convert to text?
