SVG Help

I am trying to creat a very simple svg doc using the following source
document: (August.xml)

<?xml version='1.0'?>
<?xml:stylesheet type="text/xsl" href="circle.svg.xsl"?>
<claims>
<header>August</header>
<cpu>No</cpu>
<comm>All Vendors</comm>
<claim claimable="no">
   <vendorcode>B1341</vendorcode>
   <vendorname>PILGRIMS PRIDE</vendorname>
   <vendorRollontime> 99 </vendorRollontime>
   <vendorontime> 100 </vendorontime>
   <cons> 104 </cons>
   <carrier>DETCO</carrier>
   <carrierontime> 90 </carrierontime>
   <loadnum>226347</loadnum>
   <po>1914824</po>
   <due>8/1/2004 </due>
   <original>8/1/2004 11:10:00 PM </original>
   <scheduled>8/1/2004 11:10:00 PM </scheduled>
   <actual>8/1/2004 9:28:00 PM </actual>
   <vendstat>On Time</vendstat>
   <carrierstat>On Time</carrierstat>
   <buyer>NOEL BAKER</buyer>
</claim>
...
</claims>

using the following stylesheet: (circle.svg.xsl)

<xsl:stylesheet
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"
  xmlns:svg="http://www.w3.org/2000/svg"
  xmlns:xlink="http://www.w3.org.1999/xlink">

<xsl:strip-space elements="*"/>

<xsl:output method="xml" media-type="image/svg+xml"
   indent="yes" encoding="ISO-8859-1"/>

<xsl:template match="claims">
  <svg viewBox="0 0 800 400">
    <circle r="100" cx="50%" cy="50%"
    fill="orange" stroke="black" stroke-width="10"/>
    <xsl:call-template name="markers"/>
  </svg>
</xsl:template>

<xsl:template name="markers">
  <g text-anchor="middle" font-size="20" fill="red">
  <desc>Timeline Markers</desc>
  <text x="400" y="100">This is text</text>
  <xsl:apply-templates select="header"/>
  </g>
</xsl:template>

<xsl:template match="header">
  <xsl:value-of select="."/>
</xsl:template>

</xsl:stylesheet>

I have followed the format in Jeni Tennisons book "Beginning XSLT" But all I
get is plain unformated text such as:

"Timeline Markers This is textAugust"

Can anyone solve this mystery for this befuddled newbie?
