OK, that clears things up a little. :-)

Really?  I thought <xsl:template match="/"> would match only the root
node ("/"), and if you want to do anything with the document element
you refer to it with the (implicit) child axis (e.g. "*" or "mydoc"):

  <xsl:template match="/">
    <xsl:for-each select="*">
	 <p><xsl:value-of select="name()"/></p>
    </xsl:for-each>
  </xsl:template>

which prints the name of the document element, not its children.

The same results as

 <xsl:template match="/">
   <xsl:copy-of select="*"/>
 </xsl:template>

but not the same results as

 <xsl:template match="/">
   <xsl:copy-of select="."/>
 </xsl:template>

right?

Are you sure?  Kay p. 63 seems to disagree:
[speaking of "The Tree Model", not of the raw XML text]
"For a *well-formed document* the children of the root
node will be the document element *plus any comments or processing
instructions* that come before or after the document element."
