[xsl] Error - Un declared entity reference

["V.Ramkumar" <V.Ramkumar@xxxxxxxxxxxxxxxxxxxxxx>]

Hi Friends,

I am using saxon9 for XSL(v2.0) Transform from One XML to another.

I am getting below error for entity problem.

Saxon Error :	"Error on line 61 column 53 of input.xml: SXXP0003: Error
reported by XML parser: The entity "kappa" was
			referenced, but not declared.
			Transformation failed: Run-time errors were
reported"

Line 61(XML):	contains, <title type="document">Implication of NF-
&kappa;B in 		<i>Helicobacter pylori</i>-
associated gastritis</title>

XSLT		:	<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>

			<xsl:output method="xml" indent="yes"
encoding="iso-8859-			1"/>
	
			<xsl:template match="/">
				<xsl:apply-templates/>
			</xsl:template>

Run command :

		R:\AJG>java -jar saxon\saxon9.jar -s:ajg20001-in.xml -
xsl:AJGTrans.xsl -o:ajg20001-out.xml

Earlier I used xalan for XML 2 HTML transform, but not faced this problem.

Please help.

Regards,
Ramkumar
