Xquery transformation and namespaces

Question

I'm transforming one XML document based on schema A to another XML document based on schema B. Thransformation works ok, except for the problem with namespaces. My result document looks like this:
<ns0:root xmlns:ns0="namespaceA">
     <ns0:request>
          <ns1:Element xmlns:ns1="namespaceB">value1</ns1:Element>
          <ns1:Attribute xmlns:ns1="namespaceB">value2</ns1:Attribute>
          <ns1:Attribute xmlns:ns1="namespaceB">value3</ns1:Attribute>
          <ns1:Attribute xmlns:ns1="namespaceB">value4</ns1:Attribute>
     </ns0:request>
</ns0:root>
The problem is that namespace attribute is repeated in each element. I want to declare namespaceB in root and than use only prefixes. So document should loook like this:
<ns0:root xmlns:ns0="namespaceA" xmlns:ns1="namespaceB">
     <ns0:request>
          <ns1:Element>value1</ns1:Element>
          <ns1:Attribute>value2</ns1:Attribute>
          <ns1:Attribute>value3</ns1:Attribute>
          <ns1:Attribute>value4</ns1:Attribute>
     </ns0:request>
</ns0:root>
Is it possible to achieve that, and how?
Thanks for help.

Helo!
I saw yesterday this soluction:
It's best not to think of this as "removing the namespaces" but rather as
"changing the element names". The name of an element consists of a namespace
URI and a local name. So the name of the Email element, for example, is
("urn:mpeg:mpeg7:schema:2001", "email"). In your desired result, you want an
Email element without the namespace, that is, you want the name of the
element in the result to be ("", "email"). So your query has to rename every
element, or to put it another way, it has to create an element whose name is
different from the original.
The way to do this is to write a recursive function something like this:
declare function f:strip-namespace($e as element()) as element() {
element {QName((), local-name($e)} {
for $child in $e/(@*,*)
return
if ($child instance of element())
then f:strip-namespace($child)
else $child
