[xsl] Copy results

[Steven Ericsson-Zenith <steven@xxxxxxxxxxxxx>]

Dear list,

What is the optimal way to copy a results document? So, what one would  
like perhaps is:

<xsl:result-document
                href="file1.xhtml,file2.xhtml">

</xsl:result-document>

Is the optimal way to do this to assign the page output to a variable  
and then dump it in two consecutive result-documents?

Sincerely,
Steven
