solution:

  <xsl:template match="*">
        <xsl:element name="{local-name()}" namespace="
http://www.bibletechnologies.net/2003/OSIS/namespace">
            <xsl:copy-of select="@*"/>
            <xsl:apply-templates/>
        </xsl:element>
    </xsl:template>

I was pleasantly surprised to see that xml:lang wasn't changed.
Thanks for your help.
