You shouldn't use xsl:copy-of.
This makes a deep copy without processing the inner elements.
Use xsl:copy and xsl:apply-templates - see the identity transformation
in the XSLT spec http://www.w3.org/TR/xslt#copying

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

Now you can add special templates for special element nodes, such as
innernode. But note: to process lownode you should call xsl:apply-templates
as well. So your template becomes

<xsl:template match="innernode">
	<innernode>
	I have edited this node
	<xsl:apply-templates select="*" />  <!-- only elements, no text nodes 
-->
	</innernode>
</xsl:template>

I haven't tested it, but it should work.
Cheers,
Oliver
