SAML extensions example

In Section 6 of the core spec, [XTAML] is given as an example of 
something that extends SAML assertions.  The only version of XTAML that 
I can find only is from late 2001, and if that's the most recent one 
it's certain not to conform to the current form of SAML.  This suggests 
that it's not really the best example.  An obvious candidate for an 
updated example is Liberty.  Does anyone mind if I switch to that?  Or 
do you have other suggestions?  Thanks--
