2) - Also related to the first template. Why do I need the

I would have thought in the template match "/" would have sufficed.
(When I try that, I just get the values from the nodes).

Well if you want to copy everything (the XSLT data model covers) then
<xsl:template match="/">
<xsl:copy-of select="/"/>
suffices but that is not an approach where you can work in additional templates. With the identity transformation template written as
<xsl:template match="@* | node()">
<xsl:apply-templates select="@* | node()"/>
you can add templates to override the template for nodes that you want to change. So using xsl:copy for a shallow copy and xsl:apply-templates to process attributes and child elements gives additional templates a chance to be applied on each step.
