xml declaration not written

hello,

I have a xml file:
---------------
<?xml version="1.0" encoding="ISO-8859-1"?>
<?xml-stylesheet type="text/xsl" href="in.xsl"?>
<eventi>
<evento><id>29153</id><titolo>Invito a corte</titolo></evento>
</eventi>
---------------

the in.xsl contains:
-----------------
<?xml version="1.0" encoding="iso-8859-1" ?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output version="1.0" method="xml" encoding="iso-8859-1" indent="yes"
standalone="yes" />
<xsl:template match="/">
 <milanomese>
  <test>test</test>
  <test>test</test>
  <xsl:copy-of select="eventi/evento"/>
 </milanomese>
</xsl:template>
</xsl:stylesheet>
-----------------

very simple, no?
if I open the file with a browser the xml file is trasformed ok, but the
browser doesn't include the xml declaration (<?xml version="1.0"
encoding="iso-8859-1" ?>) in the output.
I can't understand why!
as you can see I used the <xsl:output .... I think correctly.....

any idea?
