XalanJ2 XMLSerializer problems

[Gary L Peskin <ga...@firstech.com>]

I've started working quite a bit with XalanJ2.  I'm trying to port the
Nodeset extension function as a first project and the implementation is
going to have to be be somewhat different from XalanJ1.  This is because
RTFs appear to be passed as a org.apache.xerces.dom.DocumentFragmentImpl
rather than a org.apache.xalan.xslt.ResultTreeFrag.  This actually works
out better for me.  I have some further testing and investigation to see
if this is always the case.

However, I came across this problem with the outputting which seems to
be in the way that XMLSerializer is used.

To recreate the problem:

------- Input XML -------
<?xml version="1.0" encoding="UTF-8"?>
<root/>


------- Input XSL -------
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl
="http://www.w3.org/1999/XSL/Transform">
	
  <xsl:variable name="greeting">abc<h1>Hello,
World!</h1>def</xsl:variable>
	
<xsl:template match="root">
  Test of copying an RTF
  *<xsl:copy-of select="$greeting"/>*
</xsl:template>  -->
	
</xsl:stylesheet>

-------- Output XML --------
 Test of copying an RTF
 *abc<?xml version="1.0" encoding="UTF-8"?>
<h1>Hello, World!</h1>def*

-----------------------------

Note how the XML declaration comes in the middle of the output document,
just before the first element <h1>.

1.  Is someone aware of this?
2.  Is someone working on this?
3.  Can you reproduce the problem?
4.  Should I work on it?
