Database Software

I tried to transform from xml to xml using xslt2.0 on oracle 10g r2.

Based on the fact that whenever I added xslt 2.0 features such as "xsl:function","xsl:for-each-group" to stylesheet, oracle 10g gives me an error "LPX-00602: Invalid child element 'for-each-group' of element 'stylesheet'", "LPX-00602:Invalid chid element 'function" of element 'stylesheet".
I strongly suspect my oracle 10g r2 doesn't support xslt 2.0 features.
But the whitepapar says oracle 10g r2 supports xslt 2.0, I'm confused.

Now I'm searching for the posibility I didn't install full XMLDB package when I installed Oracle 10g R2 and if this is that case, what should I chek with my oracle?

Is there anyone who sucessfully used XSLT 2.0 features to transform xml-to-xml using SQL like this.

select XMLTransform(XDBURIType('/AI059.xml').getXML(),XDBURIType('/AI059.xsl').getXML()).getClobVal() from dual;

the part of stylesheet is below.
