That last sentence is a bug.  Comments and PIs before and after the
document element would also be children of the root.

That's defining the term "value" for the root node.  It means that
<xsl:value-of select="/"/> gives you the same as <xsl:value-of
select="doc"/> if doc is the document element.

The xml-stylesheet PI is accessible; the XML declaration and DTD are
not.

It depends what you mean by identity transformation.  You can do a
transformation which gives you the same abstract tree before and after.
You cannot do a transformation which gives you a byte for byte identical
XML document.  That is indeed the intent.
