XSLT2.0 in txslt

Hi Guys,
Does txslt supports XSLT 2.0 & XPATH 2.0 in TOS 4.0.2.
In forums i found that TOS uses xalan as xslt parser which only supports XSLT 1.0 & XPATH 1.0. But i also found "saxon9.jar" in "TOS-Win32-r43696-V4.0.2\lib\java\" which is a xslt parser & is compatible with XSLT 2.0 & XPATH 2.0. Which default parser do TOS 4.0.2 points to & how can we change it to use saxon instead of any other.Please reply asap.
