[xsl] how to remove namespace declarations

[Frank Marent <frank.marent@xxxxxxxxxxx>]

hi

i have to remove namespace declarations in certain elements. i.e. i  
have this one:

<Facts xmlns:html="http://www.w3.org/HTML/1998/html4";  
xmlns:xlink="http://www.w3.org/1999/xlink";>
  <lotOfElements/>
</Facts>

and i want to get this one:

<Facts>
  <lotOfElements/>
</Facts>

i can't manage to get there. even when i try to remove all attributes  
from the element

<xsl:template match="Facts">
  <xsl:copy>
    <xsl:apply-templates select="*"/>
  </xsl:copy>
</xsl:template>

does not remove these unnecessary namespaces. i was searching for an  
answer but could only find how to remove namespace prefixes. but i  
have to remove the declarations. any help is very appreciated.

best regards
frank
