Use the standard identity template with a specific template to put
<start> and all of it's descendants into the namespace:

    <xsl:template match="@*|node()">
        <xsl:copy>
            <xsl:apply-templates select="@*|node()"/>
        </xsl:copy>
    </xsl:template>

    <xsl:template match="*[ancestor-or-self::start]">
        <xsl:element name="nsprefix:{local-name()}">
            <xsl:copy-of select="@*"/>
            <xsl:apply-templates/>
        </xsl:element>
    </xsl:template>

...make sure "nsprefix" is mapped somewhere.
