OK, the namespace node that's creating the namespace declaration that
you're seeing is the one in the source document. Your html:br element
in the source document has a namespace node associated the default
namespace with the namespace 'http://fedex.com/gnsl'. My guess is that
you're copying the html:br element in your document, with something
like:

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

When you copy an element, with xsl:copy or xsl:copy-of, you copy all
its namespace nodes as well. So rather than doing that, you need to
create an element without any associated namespace nodes, which means
that you have to use xsl:element. Try using:

<xsl:template match="html:*">
  <xsl:element name="html:{local-name()}">
    <xsl:apply-templates select="@*|node()" />
  </xsl:element>
</xsl:template>
