Summary of the 3 proposed syntaxes for Policy Template

Greetings There has been an intense and healthy discussion around the syntax for Policy Templates recently, thanks to Danny Steven and Erik.
I thought that I should summarize the various proposals on the Wiki: https://wiki.oasis-open.org/xacml/Policy%20Template%20Syntactic%20Options Danny, Steven, Erik, please apologize if I missed on of your points.
I still have to double check that OOI have not forgotten anything against the email thread (I fact I have, but will correct before today close of business).
Thanks, Jean-Paul
