Next steps toward the writing of policy binding by reference and policy templates profiiles

Hi all Tomorrow during the TC call, I would like to have a discussion on the next steps to writing the two new profiles: policy binding by reference and policy templates, based upon the material gathered on the Wiki pages: https://wiki.oasis-open.org/xacml/Policy%20Reference%20Profile and https://wiki.oasis-open.org/xacml/Policy%20Template%20Profile , respectively.
Thanks, Jean-Paul Buu-Sao
