This is certainly not what you want!

Correct.

These are namespace declarations: bind a namespace-prefix to a namespace-URI.

Yes.

I would like to propose 2 stylesheets. First if you would like to use copy-of.
It moves the namespace declarations to the outermost element and works
for both xsltproc and Saxon-6:

<?xml version="1.0" encoding="UTF-8" ?>
<xsl:stylesheet version="1.0"
   xmlns:my="http://mynamespace.org/";
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
   xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output method="xml" indent="yes"/>
<xsl:template match="/">
   <body xmlns="http://www.w3.org/1999/xhtml";>
      <div>
         <xsl:copy-of select="my:entry/my:content/*"/>
      </div>
   </body>
</xsl:template>
</xsl:stylesheet>

The other solution uses the identity template and exclude-result-prefixes.
When used with xsltproc it gets rid of the namespace declarations, but
not with Saxon-6:

<?xml version="1.0" encoding="UTF-8" ?>
<xsl:stylesheet version="1.0"
   xmlns:my="http://mynamespace.org/";
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
   exclude-result-prefixes="my xsi"
   xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output method="xml" indent="yes"/>
<xsl:template match="/">
   <body xmlns="http://www.w3.org/1999/xhtml";>
      <div>
         <xsl:apply-templates select="my:entry/my:content/*"/>
      </div>
   </body>
</xsl:template>
<xsl:template match="node() | @*">
   <xsl:copy>
      <xsl:apply-templates select="node() | @*"/>
   </xsl:copy>
</xsl:template>
</xsl:stylesheet>

Hope this helps,
