You need some different rules.  "value-of" returns stripped text, not
tags.

Try this:

<xsl:template match='page'>
  <xsl:apply-templates select='content/node()|content/@*' />
</xsl:template>

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

That's a recursive template that overrides the "default" template (which
only copies node()s, not atrributes (@*), and a start-rule that will
apply that rule to the contents of any "page/content/"

One thing you might consider is putting the HTML tags in the proper
namespace -- xmlns:xhtml="http://www.w3.org/1999/xhtml", then writing
rules that match xhtml:node() instead of just any, and telling xsl to
output those tags without prefix on the output side.
