You can achieve this with

<xsl:template match="/*">
  <xsl:copy> (or <lre>)
    <xsl:copy-of select="//namespace::*"/>

However, this will also copy namespaces that aren't used in the result
document. If you want to eliminate unused namespaces AND promote retained
namespaces to the outermost element, then a two-phase transformation is
probably the cleanest way.
