Setting XSL parameter with DBMS_XMLGEN.setXSLTParam

Question

Hi all,
Here's my second post about XSL parameters. This one deals with the procedure setXSLTParam from the package DBMS_XMLGEN in 10g R2.
The test case is the following :
DECLARE
ctx dbms_xmlgen.ctxHandle;
res clob;
xsl clob := to_clob(
'<?xml version="1.0" encoding="iso-8859-15"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="html" version="4.0" encoding="iso-8859-15"/>
<xsl:param name="caption"/>
<xsl:template match="/">
<TABLE>
  <CAPTION><xsl:value-of select="$caption"/></CAPTION>
  <xsl:apply-templates/>
</TABLE>
</xsl:template>
<xsl:template match="ROWSET">
<TR>
  <xsl:for-each select="ROW[1]/*">
   <TH><xsl:value-of select="local-name()"/></TH>
  </xsl:for-each>
</TR>
<xsl:apply-templates/>
</xsl:template>
<xsl:template match="ROW"><TR><xsl:apply-templates/></TR></xsl:template>
<xsl:template match="ROW/*"><TD><xsl:value-of select="."/></TD></xsl:template>
</xsl:stylesheet>');
BEGIN
ctx := dbms_xmlgen.newContext('select level from dual connect by level < to_number(:MAXLINE)');
dbms_xmlgen.setXSLT(ctx, xsl);
dbms_xmlgen.setXSLTParam(ctx, 'caption', '"TEST"');
dbms_xmlgen.setBindValue(ctx, 'MAXLINE', '10');
res := dbms_xmlgen.getXML(ctx);
dbms_xmlgen.closeContext(ctx);
END;Execution gives error "*ORA-31020: The operation is not allowed, Reason: Invalid XSL Parameter or its Value*".
I think I'm using the correct syntax for the parameter, but the procedure doesn't seem to work properly (it's also not documented explicitly for Oracle 10gR2).
Its java-based counterpart DBMS_XMLQUERY.setXSLTParam() works well though.
Has anyone ever managed to use this feature in 10g or newer release?
Thanks.

NLSRTL Version 10.2.0.1.0 - Production for me your code is work. result:

<TR>
<TH>LEVEL</TH>
</TR>
<TR>
<TD>1</TD>
</TR>
<TR>
<TD>2</TD>
</TR>
</TABLE>some interesting note:
xslt CLOB := '<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes" omit-xml-declaration="no"/>
...In 10.2 when XSLT is used with dbms_xmlgen the XML Header tag is missing
may be this help you
