RE: [xsl] RE: result document flush

Hi all,

The issue has been resolved (at least I now know how to get my more complex use 
case working).

I created a simplified version to spin my head around the issue of splitting 
several XML files into separate files. The issue I ran into was having 
duplicate URI's to write to.  It would be satisfying to e.g. skip duplicate 
entries from being processed so here are my inputs and a working solution. Any 
improvements are welcome of course ;-)

The manifest.xml is the input for the XSLT by the way.
-----------------------manifest.xml-----------------------

<?xml version="1.0" encoding="UTF-8"?>
<manifest>
  <file href="basictypes.xml"/>
  <file href="packages.xml"/> 
</manifest>

-----------------------basictypes.xml-----------------------
<?xml version="1.0" encoding="UTF-8"?>
<basictypes>
    <basictype identifier="PH3330L">
        <description>N-channel TrenchMOS logic level FET</description>
        <magcode>R73</magcode> 
    </basictype>
    <basictype identifier="BUK3F00-50WDFE">
        <description>9675 AUTO IC (IMPULSE)</description>
        <magcode>R73</magcode>   
    </basictype>
    <basictype identifier="PH3330L">
        <description>duplicate entry for PH33330L</description>
        <magcode>R73</magcode> 
    </basictype>    
</basictypes>

-----------------------packages.xml-----------------------
<?xml version="1.0" encoding="UTF-8"?>
<packages>
    <package id="SOT669">
        <description>plastic single-ended surface-mounted package; 4 
leads</description>
        <name>LFPAK; Power-SO8</name> 
    </package>
    <package id="SOT600-1">
        <description>plastic thin fine-pitch ball grid array
