Also, if you obtain the principal result _document_ or a document 
generated by xsl:result_-document- via an API that doesn't serialise the 
result but hands over the XDMnodes you will get a document node.

<xsl:stylesheet   ...>
<xsl:template match="*">
   <xsl:copy/>
</xsl:template>
</xsl:stylesheet>

doesn't use xsl:document, and doesn't copy the document node of its 
input, but does generate a document node with a copy of the top level 
element of its output.
